fluent经典算例Tutorial:Modeling a Single-Channel,Counter-Flow Polymer Electrolyte Membrane(PEM)Fuel CellIntroductionThe purpose of this tutorial is to provide guidelines and recommendations for using the PEM Fuel Cell add-on module available in FLUENT.This tutorial demonstrates how to do the following:Build and generate a mesh for a single-channel PEM fuel cell.Assign zone names and types that are required in the FLUENT PEM fuel cell add-onmodule.Import the mesh into FLUENT,set up the case,and run the calculations.Postprocess the results.PrerequisitesThis tutorial assumes you are familiar with both the GAMBIT and FLUENT interfaces and that you have a good understanding of the basic setup and solution procedures.Details of most steps will not be shown explicitly.If you have not used FLUENT before,it would be helpful to?rst refer to the FLUENT6.3 User’s Guide and theFLUENT6.3Tutorial Guide.You can also refer to the GAMBIT User’s Guide,GAMBIT Tutorial Guide,and GAMBIT Modeling Guide.Problem DescriptionA schematic description of a single,straight-channel,counter-?ow PEM fuel cell is shown inFigure1.The dimensions of the fuel cell are2.4×2.88×125mm in the x,y,and z directions, respectively.This model represents a repeating channel of a larger counter-?ow PEM fuel cell.The cross-sectional area of the membrane electrode assemblyis2.4×125=300mm2.All the zones as marked in Figure1(with exception of the optional cooling channel)must be de?ned as separate zones within GAMBIT.Note that there can be multiples of each zone.For example,there can be multiple cathode gas di?usion layers,each with di?erent material properties.In FLUENT6.3,all continuum zones must be of the?uid type except for the current collectors which may be either solid or? uid.For simplicity,it is recommended that you make the current collectors solid continuum zones.Modeling a Single-Channel,Counter-Flow Polymer Electrolyte Membrane(PEM)Fuel CellFigure1:PEM Fuel Cell ZonesFor details about the FLUENT PEMFC model,refer to o f FLUENT6.3Fuel Cell ModulesManual.Note:If you would like to bypass all GAMBIT steps and proceed to the FLUENT portion of the tutorial,skip to Step. Preparation in GAMBIT1.Create a folder called pem-single-channel to contain the?les generated in thistutorial.2.Start GAMBIT and specify this folder as the working folder.To simplify the geometry construction and meshing steps,a journal?le,pem-single-channel.jou is provided.This?le contains GAMBIT instructions which will create the geometry and gen-erate the mesh.It is recommended that you step through the journal?le to understand eachof the steps and recognize the assigned zone boundary types pertinent to fuel cell problems.Geometry Creation and Mesh GenerationStep1:Geometry Creation1.Create a rectangular face primitive in the xy plane.Operation?→Geometry?→Face?→Create Real Rectangular Face(a)Enter2.4for Width and1.2for Height.Modeling a Single-Channel,Counter-Flow Polymer Electrolyte Membrane(PEM)Fuel Cell(b)Select+X+Y for Direction,(c)Click Apply and close the Create Real Rectangular Face panel.2.Create another face by sweeping the uppermost edge by0.21units in the y-direction.Operation?→Geometry?→Face?→Sweep Edges3.Create another face by sweeping the uppermost edge by0.012units in the y-direction.4.Create another face by sweeping the uppermost edge by0.036units in the y-direction.5.Create another face by sweeping the uppermost edge by0.012units in the y-direction.6.Create another face by sweeping the uppermost edge by0.21units in the y-direction.7.Create another face by sweeping the uppermost edge by1.2units in the y-direction.8.Create a rectangular face with dimensions(x,y)=(0.8,0.6).Use+x+y for the di-rection(so that the global coordinate system origin is in the lower left corner of theface).9.Move the newly created face using a vector of(0.8,0.6,0).Operation?→Geometry?→Face?→Move/Copy Faces10.Copy the face by1.08units in the y-direction.11.Split the lowermost face with the face you just created.Operation?→Geometry?→Face?→Split Face12.Similarly,split the uppermost face with its internal face.The resulting mesh should appear as shown in Figure2.Step2:Mesh Generation(Manual)1.Mesh the edges as shown in Figure2.The numbers of cells along each edge are indicated below.The geometry and mesh are symmetric about its horizontal midplane.Operation?→Mesh?→Edge?→Mesh Edges2.Mesh the nine faces using the Quad Submap scheme.Operation?→Mesh?→Face?→Mesh Faces3.Create an edge by sweeping any one of the vertices by125units in the positive z direction.Operation?→Geometry?→Edge?→Sweep VerticesModeling a Single-Channel,Counter-Flow Polymer Electrolyte Membrane(PEM)Fuel CellFigure2:Edge and Face Mesh(a)Select Vector for Path and click the De?ne button.(b)Enable Magnitude and enter125.(c)Select Positive for Z from the Direction list.(d)Click Apply in the Vector De?nition form.(e)Click Apply and close the Sweep Vertices form.4.Mesh the newly created edge using a double-sided graded edge mesh that consists of 60elements.(a)Enable Double sided.(b)Enter1.1for Ratio1and Ratio2.(c)Click Apply and close the Mesh Edges form.5.Create volumes by sweeping the nine faces along the newly created edge. Operation?→Geometry?→Volume?→Sweep Faces(a)Enable With Mesh.(b)Click Apply and close the Sweep Faces form.The volume mesh is as shown in Figure3.Modeling a Single-Channel,Counter-Flow Polymer Electrolyte Membrane(PEM)Fuel CellFigure3:Volume MeshStep3:Zone Assignments and Mesh ExportFLUENT’s PEM fuel cell add-on module requires that boundary and continuum zones berigorously de?ned.Care should be taken in order to have a logical system of naming eachzone to represent each of the regions shown in Figure1.At a minimum,the boundary zones that are required include the following:Inlet and outlet zones for the anode gas channel.Inlet and outlet zones for the cathode gas channel.Surfaces representing anode and cathode terminals.Optional boundary zones that could be de?ned include any voltage jump surfaces,interiorow surfaces,or non-conformal interfaces that are required.The following continuum zones are also required:Flow channels for anode-and cathode-sideuids.Anode and cathode current collectors.Anode and cathode gas diusion layers.Anode and cathode catalyst layers.Electrolyte membrane.The inlets should all be assigned the boundary zone type MASS FLOW INLET and outletsshould be assigned the PRESSURE OUTLET type.The terminals are the regions where thevoltage(or current?ux density)is known.Normally,the anode is grounded(V=0)andModeling a Single-Channel,Counter-Flow Polymer Electrolyte Membrane(PEM)Fuel Cell the cathode terminal is at a?xed potential that is less than the open-circuit potential.Bothof the terminals should be assigned the WALL boundary type.Voltage jump zones can optionally be placed between the various components(such asbetween the gas di?usion layer and the current collector).Faces which represent?uid/solidinterfaces must be of type WALL.Additional interior zones may be de?ned for purposes of post-processing.If such interiorzones are de?ned,they should have no e?ect on the solution.FLUENT’s PEM add-on module supports the use of non-conformal grid interfaces.In such cases,it is recommended that the INTERFACE boundary type be used halfway between the membrane continuum zone,and that the mesh on opposite sides of the interface have similar size,aspect ratio,and orientation.In such cases,the membrane will consist of two uid zones.1.Assign boundary zones according to the de?nitions listed in Table1.Operation?→Zones?→Specify Boundary TypesTable1:Boundary Zone AssignmentsAnode-side inlet(z=125,upper)inlet-a MASS FLOW INLETCathode-side inlet(z=0,lower)inlet-c MASS

direction of?ow.7.Verify that global conservation of mass is observed.This will be done using a few text user interface(TUI)commands and basic electrochemistry concepts.(a)Compute the net oxygen consumption.Enter the TUI command:/report/species-mass-flowIf you have read a data?le instead of performing iterations,you must performat least one iteration in order to populate this data from the

follows:zone22(inlet-a):(4.8e-0701.2e-07)zone21(inlet-c):(01e-065e-07)zone20(outlet-a):(-4.6958153e-07-8.9805489e-11-2.8157297e-07)zone19(outlet-c):(-2.6251551e-10-9.1930928e-07-4.2904232e-07)zone53(wall-ch-a-shadow):(000)zone15(wall-ch-c):(000)zone29(wall-ends:029):(000)zone30(wall-ends:030):(000)zone31(wall-ends:031):(000)zone32(wall-ends:032):(000)zone33(wall-ends:033):(000)Modeling

calculated.Here,we are considering three species,namely h2,o2and h2o.Therefore,the second value in each list is the calculatedoxygen mass?ow rate in kilograms per second.In addition,a negative numberindicates?ow out of the domain from that boundary.From the last line,the netoxygen consumed is8.06×10?8kg/s.The molecular weight of oxygen is31.9988kg/kmol.Also,since the valence of a diatomic oxygen molecule is4,there are4kmol of electrons released per kmol of oxygen.Finally Faraday’s constant is9.6485×107C/kmol-electrons.Thus,the total release of electrons(which isequivalent to the current in Amperes),isI=˙mv FM=(8.06×10?8)(4.0)(9.6485×107)31.9988=0.972A(1)The total current is obtained by integrating the current density over the surface of the terminal.This integral value can be calculated in several ways.One way is to multiply the membrane area by the reported current density.This givesI=(0.0003)(0.3241)(100)2=0.972A(2) Alternatively,you can integrate the user memory Y Current Flux Density(the y-component of current density)over the terminal surface.This integration yields an accurate result since the y-direction is normal to the terminal.To do this, use the Surface Integrals panel.Report?→Surface Integrals...i.Select Report Type from the Integral drop-down list.ii.Select User De?ned Memory...and Y Current Flux Density from the Field Variable drop-down lists.iii.Select wall-terminal-a from the Surfaces selection list and click Compute.The absolute value of the number reported is approximately0.972A.We have electrochemical balance in the calculations. iv.Close the Surface Integrals panel.Modeling a Single-Channel,Counter-Flow Polymer Electrolyte Membrane(PEM)Fuel CellSummaryIn this tutorial,you learned how to set up and model a single-channel PEM fuel cell.Themodel provides detailed information on the distribution of current and voltage on all theelectrically conducting regions,along with species and current?ux density

ENBM 第一章 知识点

ENBM 第一章 知识点

第一章计算机组装与维护知识点1. 什么是适配卡?对于外部设备,CPU是无法直接控制的,它需要一种装置,将这些外部设备与主板相联,再通过系统总线实现CPU控制,这种装置就是适配卡。

2. 什么是总线?多个功能部件共享的信息传输线路称为总线。

3.什么是CPU的主频?CPU内核工作的时钟频率,其它硬件相同的情况下,主频越高,运算速度越快。

4.主频是CPU的工作频率,那么,什么是外频?什么是倍频?外频:CPU与内存之间进行数据交换的通道的工作频率。

主频与外频和倍频的关系:主频=外频×倍频。

5.什么是CPU的缓存?CPU与内存的读取速度之间存在着很大的差异,这种造成了处理器工作效率的降低。

为了缓解这种差异,在CPU与内存之间加入了一个容量较小、数据交换速度很快的临时存储器,我们常称它为高速缓存,英文写作Cache。

数据先从内存调入Cache,CPU从Cache 中读取数据。

为了进一步提高CPU的工作效率,在CPU与内存之间添加了第二个Cache,称之为二级缓存。

目前,一般情况下,一级缓存和二级缓存内置于CPU中。

6..什么是双核处理器?简单的说,所谓双核处理器就是在一个处理器基板上集成两个功能相同的处理器核心,即将两个物理处理器核心整合入一个内核中。

7.双核处理器的优势是什么?第一,双核技术的引入是提高处理器性能的行之有效的方法。

由于生产技术的限制,传统通过提升工作频率来提升处理器性能的作法目前面临严重的阻碍,高频 CPU的耗电量和发热量越来越大,已经给整机散热带来十分严峻的考验。

双核技术可以很好的避免这一点。

增加一个内核,处理器每个时钟周期内可执行的单元数将增加一倍。

第二,引入双核架构也将可以全面增加处理器的功能,这是一个十分重要的影响因素。

双处理器架构的引入和微软下一代Longhorn(Vista)操作系统将在很大程度上促进虚拟技术的发展。

8.列举市场上主流的CPU产品。

Intel的奔腾、赛扬;AMD的K系列;Cyrix的Cyrix系列。

高密度交换系统7001说明书

高密度交换系统7001说明书

w w w .k e i t h l e y.c o m1781787001 High Density Switch SystemThe 7001 is a half-rack, high-density, two-slot mainframe with the highest density switching of any half-rack mainframe in the test and measurement market.Up to 80 channels of 2-pole switching.Each slot of the 7001 can accommodate up to 40 channels. This means fewer switch cards are required, reducing switching hardware needed. Higher density also pro-vides extra capacity and flexibility.The 7001’s analog backplane is used by the high density switch cards. The backplane eliminates inter-card wiring and increases configuration flexibility. Two cards may be connected through the backplane to create a 1×80 multiplexer, a 4×20 matrix, or a multiplexer/matrix combination that provides matrix row expansion.See the status of every channel simultaneously.The vacuum fluorescent display of the 7001 shows the open/close status of each channel in the mainframe simultaneously. The graphical display pattern makes it much easier to configure a test system, make modifications, or debug an existing program. The status of the cards in both slots is displayed side by side on the same screen.Easy to Set Up and Use.The 7001 has a number of built-in features that make it easy to set up, run,change, or modify. It conforms to IEEE-488.2 and SCPI (Standard Commands for Programmable Instruments). All aspects of the instrument can be programmed from the front panel and over the IEEE bus.Simply select the channels to be scanned and enter them into the scan list. Channels can be entered in any order, and complete switch pat-terns contained in memory can also be included. Once you’ve pro-grammed a test configuration into the mainframe, you can store it in one of 10 nonvolatile memory locations. To repeat the test, simply recall the setup. Or use a setup as your power-up default.All of the programmable capability of the 7001 is saved as part of the configuration. Saving the scan list along with the other parameters also saves all of the programmable functions necessary for a complete application.Trigger-Link•Flexible: 6 lines for use with multiple instruments. Software recon-figurable.•Fast: Eliminates IEEE-bus command overheads.•Provides tighter control. Minimizes latency and jitter.•Easy to use.A C C E S S O R I E S AVA I L AB L ECABLES,ADAPTERS 7007-1Shielded IEEE-488 Cable, 1m (3.3 ft)7007-2Shielded IEEE-488 Cable, 2m (6.6 ft)8501-1Trigger Link Cable, 1m (3.3 ft)8501-2Trigger Link Cable, 2m (6.6 ft)8502Trigger Link Adapter BoxRACK MOUNT KITS4288-1Single Fixed Rack Mount Kit 4288-2Dual Fixed Rack Mount Kit OTHER 7001-EW 1 Year Warranty Extension KPCI-488IEEE-488 Interface/Controller for the PCI BusKPC-488.2AT IEEE-488 Interface Card for IBMPC/AT (full slot)KPC-TM Trigger Master Interface TestPointTest Development SoftwareSee pages 170–173 for Switching Cards and Accessories Selector Guides, and page 235 for descriptions of all accessories.1981w w w .k e i t h l e y.c o m179179ANALOG BACKPLANESIGNALS:Four 3-pole rows (Hi, Lo, Guard).

pt的交换电流密度

pt的交换电流密度

pt的交换电流密度交换电流密度(current density)是指在导体中通过的电流单位面积。

在电路中,交流电流密度是一个重要的物理量,它描述了电流在导体中的分布情况。

本文将从交流电流密度的定义、计算方法以及应用等方面进行阐述。

交流电流密度的定义:交流电流密度J表示单位面积上的电流,其计算公式为J=I/A,其中I表示通过导体的电流,A表示导体所占的面积。

交流电流密度可以用来描述电流在导体中的流动情况,通过不同面积上的电流密度可以了解电流的分布情况。

交流电流密度的计算方法:对于均匀导体,可以通过测量导体上的电流和导体的面积来计算交流电流密度。

对于非均匀导体,可以通过测量导体上不同位置的电流和对应面积来计算不同位置的交流电流密度。

值得注意的是,交流电流密度是一个矢量量,它的方向与电流的方向一致。

进一步,交流电流密度的应用:交流电流密度在电路设计和电器工程中具有重要的应用价值。

通过合理设计导体的截面形状和尺寸,可以使交流电流在导体中得到均匀的分布,从而提高电路的效率和稳定性。

Dmol、Castep的基本原理和参数设置

Dmol、Castep的基本原理和参数设置

Tips:对于空体积较大的晶体,使用DMol3的效率要高于Castep
在DMol3模块中,电子密度实际上由各个原子轨道的平方和来确定:
在这里,电子密度实际上是由所有占据的分子轨道φi.来决定。分子轨道 可能由上自旋电子(Alpha电子)和下自旋电子(Beta电子)占据。当Alpha电子和 Beta电子的数目相等的时候,我们可以用单一的分子轨道φi.来进行表述,这类 体系称为闭壳层体系(Closed-shell),在DMol3中不需要选中Spin restricted前 面的选项。当Alpha电子和Beta电子的数目不相等的时候,我们将会使用不同 的φi.来表述Alpha电子和Beta电子,这类体系称之为开壳层体系(Openedshell)或者自t旋o t极a a l化lp 。 hba 在etDaMol3计算的时候需要选中Spin restricted的选项,并 指定自旋数目。

交换电流密度概念
电极反应处于平衡时,电极反应的两个方向进行的速度相等,此时的反应速度叫做交换反应速度。

相应的按两个反应方向进行的阳极反应和阴极反应的电流密度绝对值叫做交换电流密度,用jo表示。

其大小除受温度影响外,还与电极反应的性质密切相关,并与电极材料和反应物质的浓度有关。

测量方法:测出电流的变化情况,即得到电流关于时间的函数表达式。

然后测出导线的面积。

J=delta I/delta S
某些电极反应在室温下的交换电流密度:
电极材料溶液组成电极反应jo/(A/cm2)
Hg 0.5mol/L H2SO4 H+ +e=H2 5×10-13
Ni 1.0mol/L NiSO4 1/2Ni2+ +e=1/2Ni 2×10
Fe 1.0mol/L FeSO4 1/2Fe2+ +e=1/2Fe 10-8
Cu 1.0mol/L CuSO4 1/2Cu2+ +e=1/2Cu 2×10-5
Zn 1.0mol/L ZnSO4 1/2Zn2+ +e=1/2Zn 2×10-5
Pt 0.1mol/L ZnSO4 H+ +e=H2 10×10-4
氧还原是一个复杂的四电子过程,交换电流密度小,可逆性差,过电位高。

碱性溶液中,氧在贵金属上的交换电流密度仅为约10-10A/cm2, 比同一金属上氢的交换电流密度10-3A/cm2低6-7个数量级。

贵金属铂及其合金具有很高的催化活性、稳定性和导电性,但价格昂贵、易中毒,无法大规模商业化使用。

除此之外的氧还原催化剂还有过渡金属氧化物(钙钛矿型、焦绿石型氧化物、尖晶石型)、过渡金属有机大环化合物等。
