北航《建筑备》第一章 流体力学基本知识 课堂笔记

北航《建筑备》第一章 流体力学基本知识 课堂笔记

北航《建筑设备》第一章流体力学基本知识课堂笔记◆主要知识点掌握程度重点掌握流体运动的基本知识;熟悉流体的静压强及分布;了解流体的主要物理性质;了解流体阻力的流动状态。

◆知识点整理一、建筑设备绪论(一)建筑设备的作用建筑设备对于现代建筑的作用,好比人的五脏对了人的作用相似。

如果把建筑外形、结构及建筑装修比作人的体形、骨路及服饰,那么,建筑设备可比作人的内脏及器官。

空调与通风好比人的呼吸系统。

室内给排水好比人的肠胃系统。

供配电好比人的供血系统。

自动控制与弱电好比人的神经及视听系统。

人的外形与内部器官和建筑外形与设备,均是互为依存。

缺一不可的。

从经济上看,一座现代建筑物的初投资产,土建、设备与装修,大约各占三分之一左右。

现代化程度愈高.设备及装修所占的比例愈大。

从建筑物的使用成本看,建筑设备的设汁及其性能的优劣,耗能的多少,是直接影响经济效益的重要因素。

一座星级宾馆,假如其空调效果很差或供电系统经常故障而停电.或通讯系统不完善、不方便,不可想象其经济效益及使用效果会是令人满意的。

(二)建筑设备的特点1、时代性。

2、节能与低污染。

3、多学科综合性。

(三)建筑设备的种类现代建筑设备内容广泛,种类繁多。

从其作用可分以下四类:1、创造环境的设备:如创造空气温、湿度环境的空调设备等;2、追求方便的设备:如通讯、电梯、卫生器具等;3、增强安全的设备:如报警、防火、防烟、防盗、防振等;4、提高控制性及经济性设备:如自动控制、电脑管理等。

从专业分,—般包括以下各专业:空调通风与采暖、给排水、供配电、弱电、动力、环保、洗衣设备、厨房设备、运输设备等。

(四)建筑设备的内容1、空调与通风设备(1)冷源设备(2)热源设备(3)空调及通风设备(4)防排烟设备2、室内给徘水设备3、供配电设备4、弱电设备5、环保设备6、洗衣设备7、厨房设备8、室内垂直运输设备(电梯)9、娱乐及健身设备二、流体的主要物理性质(一)流体的密度和容重流体单位体积的质量称为流体的密度,用ρ表示,即ρ=(1——1)/m V式中ρ——液体的密度(kg/m 3);m ——液体的质量(kg );V ——液体的体积(m 3);流体也和固体一样具有重量,这是物质受地球引力产生的。

北航研究生课程实验流体力学重点第一章:相似理论和量纲分析①流体力学相似?包括几方面内容?有什么意义?流体力学相似是指原型和模型流动中,对应相同性质的物理量保持一定的比例关系,且对应矢量相互平行。

内容包括:1.几何相似—物体几何形状相似,对应长度成比例;2.动力相似—对应点力多边形相似,同一性质的力对应成比例并相互平行 (加惯性力后,力多边形封闭);3.运动相似—流场相似,对应流线相似,对应点速度、加速度成比例。

②什么是相似参数?举两个例子并说明其物理意义必须掌握的相似参数:Ma ,Re ,St 。

知道在什么流动条件下必须要考虑这些相似参数。

相似参数又称相似准则,是表征流动相似的无量纲特征参数 。

1.两物理过程或系统相似则所有对应的相似参数相等。

例如:假定飞机缩比模型风洞试验可以真正模拟真实飞行,则原型和模型之间所有对应的相似参数都相等,其中包括C L , C D , C M :S V LC L 221ρ=S V DC D 221ρ=SbV MC M 221ρ=风洞试验可以测得CL, CD, CM 值,在此基础上,将真实飞行条件带入CL, CD, CM 表达式,可以求得真实飞行的升力、阻力和力矩等气动性能参数。

2.所有对应的相似参数相等且单值条件相似则两个物理过程或系统相似。

例如:对于战斗机超音速风洞试验,Ma 和Re 是要求模拟的相似参数,但通常在常规风动中很难做到。

由于对于此问题,Ma 影响更重要,一般的方案是保证Ma 相等,对Re 数影响进行修正。

;R e V pM a a RTaV L l St Vρρωμ∞∞=====Ma 为惯性力与弹性力之比,在可压缩流动中考虑。

Re 为惯性力与粘性力之比,在粘性流动中考虑。

St 为无量纲频率,在周期性流动中考虑。

另,通常风洞模型试验模拟飞行器试验要满足的主要相似参数: 超音速:Ma 和Re (需要同时考虑压缩性和粘性影响);低速(Ma<0.3 ):Re (压缩性影响可忽略,只考虑粘性影响)。

(2)油的粘度液体的粘性用粘度来表示。

常用的粘度:动力粘度、运动粘度和相对粘度①动力粘度μ(绝对粘度)物理意义:当速度梯度等于1时,接触液体层间单位面积上的内摩擦力。

国际单位SI:N⋅s/m2,简称:Pa⋅s,工程单位CGS:dyn⋅s/cm2,简称:P (泊)。

换算关系:1Pa⋅s = 10 P =103cP②运动粘度ν国际单位SI:m2/s;ρμν=dudyτμ=工程单位CGS :cm 2/s ,简称:St(斯)。

mm 2/s ,简称:cSt(厘斯)。

换算关系:1m 2/s = 104cm 2/s = 104 St = 106 cSt10号机械油:该油在50︒时运动粘度的平均值为10mm 2/s ,ν50=10cSt相对粘度以相对于水的粘度大小来度量油的粘度大小,︒E t = t 油/t 水 恩氏粘度。

为了理论分析和计算而引出。

(3) 粘度与压力的关系p νp ν一般液压系统的压力较低,可以认为不变;当压力较大 p >100bar ,则需考虑。

层流:是流体地一种流动型态,这种型态地特征是流体运动规则、稳定,流体层之间没有宏观地横向掺混.湍流:是流体地另一种流动型态,这种型态地特征是流体在总地运动趋势上,还存在各个方向上地随即脉动,流体层之间出现显著地横向掺混.文档收集自网络,仅用于个人学习层流和湍流是实际存在地流动型态,是流体在微元尺度上地流动状况.二者地判定主要通过雷诺数来完成,一般认为<为层流,>为湍流,中间为过渡流.文档收集自网络,仅用于个人学习壁面率:在研究管内湍流时用到通用速度分布(壁面率):该假设将管内流动分为三个区域,分别为粘性底层区、过渡区和湍流核心区.在粘性底层通常认为粘性应力大于雷诺应力,表现出层流特性,速度分布体现出线性特征;而在湍流核心区,雷诺应力远大于粘性应力,体现出湍流特性,速度分布呈对数分布.在过渡区粘性应力和雷诺应力量级相当,速度分布特征主要通过试验确定,也有一些经验公式.文档收集自网络,仅用于个人学习粘性应力:层流流动中流体层之间由于流体本身粘性作用引起地切应力.雷诺应力:湍流流动中流体层之间除了粘性性应力之外,还存在由于湍流脉动引起地附加切应力.也叫湍流切应力.文档收集自网络,仅用于个人学习势流与粘性流势流与粘性流是为方便研究而假设地流动,这两种流动主要应用于不可压缩流体.势流:是在大雷诺数时,流体地粘性力远小于惯性力,在忽略粘性力进行计算时地一种流动.湍流核心区常简化为势流进行计算.一般在理想流体(μ)中讨论有势流动地情况.文档收集自网络,仅用于个人学习粘性流:是在小雷诺数时,流体地粘性力不能忽略时进行计算地一种流动.层流或湍流粘性底层常简化为粘性流进行计算.粘性流都是有旋流动.文档收集自网络,仅用于个人学习有势流动地充要条件是无旋,即流体微团涡量为零,表示为:0=∇⨯=Ωu .流体流动地基本方程: 连续性方程:()0t ρρ∂∇⋅+=∂u以应力表示地运动方程: ()()()yx x x x x x xx zx x y z x y y y y y xy yy zyx y z y yz xz z z z z z zzx y z z du u u u u v v v f dt t x y z x y zdu u u u u v v v f dt t x y z x y z du u u u u v v v f dt t x y z x y z τστρρρτστρρρττσρρρ∂∂∂∂∂∂∂=+++=+++∂∂∂∂∂∂∂∂∂∂∂∂∂∂=+++=+++∂∂∂∂∂∂∂∂∂∂∂∂∂∂=+++=+++∂∂∂∂∂∂∂在粘性流体中将牛顿本构方程代入上面运动方程后表示就得到以应力表示地粘性流体运动微分方程——方程:文档收集自网络,仅用于个人学习2()2()[()][()]32()[()]2()[()]32()[(3y x x x x z x y y y y x z y x z z u du u u u u p f dt x x x x y y x z z xdu u u u u u p f dt y y x y x y y z z yu du p f dt z z x z ρρμμμμρρμμμμρρμμ∂∂∂∂∂∂∂∂∂∂=--∇⋅+++++∂∂∂∂∂∂∂∂∂∂∂∂∂∂∂∂∂∂∂∂=--∇⋅+++++∂∂∂∂∂∂∂∂∂∂∂∂∂∂=--∇⋅++∂∂∂∂u u u )][()]2()y z z z u u u u x y z y z zμμ∂∂∂∂∂∂+++∂∂∂∂∂∂ 牛顿本构方程:22()322()322()3()()()y x x z xx y y x z yy y x z z zz y x xy yx y z yz zy x z zx xz u u u u p x x y zu u u u p y x y zu u u u p z x y z u u y xu u z yu u x z σμμσμμσμμττμττμττμ∂∂∂∂=-+-++∂∂∂∂∂∂∂∂=-+-++∂∂∂∂∂∂∂∂=-+-++∂∂∂∂∂∂==+∂∂∂∂==+∂∂∂∂==+∂∂ 理想流体地运动方程:令方程中地粘度μ,也称欧拉方程. 在理想流体中才讨论有势流动地情况.流体静力学方程:令方程中地所有速度项为.常粘度下地方程:(其中:μ)22222222222222211()311()311()3x x x x x y y y y y z z z z z du u u u p f dt x x y z x du u u u p f dt y x y z y du u u u p f dt z x y z z ννρννρννρ∂∂∂∂∂∇⋅=--+++∂∂∂∂∂∂∂∂∂∂∇⋅=--+++∂∂∂∂∂∂∂∂∂∂∇⋅=--+++∂∂∂∂∂u u u 矢量形式为:211()3d p dt ννρ=-∇-∇+∇∇⋅u f u u 不可压缩常粘度流体地方程:(其中ρ,且∇⋅u ) 2222222222222221()1()1()x x x x x y y y y y z z z z z du u u u p f dt x x y zdu u u u p f dt y x y zdu u u u p f dt z x y zνρνρνρ∂∂∂∂=--++∂∂∂∂∂∂∂∂=--++∂∂∂∂∂∂∂∂=--++∂∂∂∂ 矢量形式为:21d p dt νρ=-∇-∇u f u 后面附上基本向量算子及算法.。

流体力学复习资料及英文专有名词解释

Chapter 1 Fluid statics 流体静力学1. 连续介质假定(Continuum assumption):The real fluid is considered as no-gap continuousmedia, called the basic assumption of continuity of fluid, or the continuum hypothesis of fluid.流体是由连续分布的流体质点(fluid particle)所组成,彼此间无间隙。

它是流体力学中最基本的假定,1755年由欧拉提出。

在连续性假设之下,表征流体状态的宏观物理量在空间和时间上都是连续分布的,都可以作为空间和时间的函数。

2. 流体质点(Fluid particle ): A fluid element that is small enough with enough moles to makesure that the macroscopic mean density has definite value is defined as a Fluid Particle. 宏观上足够小,微观上足够大。

3. 流体的粘性(Viscosity ): is an internal property of a fluid that offers resistance to sheardeformation. It describes a fluid's internal resistance to flow and may be thought as a measure of fluid friction. 流体在运动状态下抵抗剪切变形的性质,称为黏性或粘滞性。

它表示流体的部流动阻力,也可当做一个流体摩擦力量。

The viscosity of a gas increases with temperature, the viscosity of a liquid decreases with temperature. 4. 牛顿摩擦定律(Newton ’s law of viscosity ):5. The dynamic viscosity (动力黏度)is also called absolute viscosity (绝对黏度). The kinematicviscosity (运动黏度)is the ratio of dynamic viscosity to density.6. pressibility (压缩性):As the temperature is constant, the magnitude of pressibility isexpressed by coefficient of volume pressibility (体积压缩系数) к , a relative variation rate (相对变化率) of volume per unit pressure.The bulk modulus of elasticity (体积弹性模量) E is the reciprocal of coefficient of volumepressibility к.7. 流体的膨胀性(expansibility; dilatability):The coefficient of cubical expansion (体积热膨胀系数) αt is the relative variation rate of volume per unit temperature change.du dzτμ=μνρ=8. 表面力Surface tension : A property resulting from the attractive forces betweenmolecules.σ-----单位长度所受拉力 9. 表面力 Surface force ——is the force exerted on the contact surface by the contacted fluid orother body. Its value is proportional to contact area.作用在所研究流体外表面上与表面积大小成正比的力。
