如果我们忽视动能和势能变化,净工作输出是 T 的图下的区域。由图 1-5(b) ; 区 1-2-3-4-1由于第一定律需要 W=Q.The 传热工作的实质内容由一-2-3-b-一区,情况也是如此。
因此,朗肯循环的热效率 n 是
(1-2).
所需的输出,即除以能量输入 (购买能源)。
Obviously,the thermal efficiency can be improved by increasing the numerator or by decreasing the denominator. This can be done by increasing the pump outlet pressure P2, increasing the boiler outlet temperature T3 or decreasing the turbine outlet pressure P4.
显然,通过增加分子或通过减小分母可以提高热效率。这可以通过增加泵出口压力 P2,锅炉出口温度 T3 的增加或减少涡轮出口压力 P4。
1.1。8 再热循环
很明显与高锅炉压力或低凝汽器压力朗肯循环中运行时很难防止液滴在低压涡轮的部分形成。由于大多数金属不能经受温度约 600 以上,再热周期通常用于防止液体滴形成: 蒸汽涡轮机穿越在一些中间的压力,从而提高 5 中的状态 T 的图图 1-6 的温度加热。然后的蒸汽涡轮低压条经过和进入状态 6 冷凝器。这控制或完全消除了在涡轮中的水分问题。通常,涡轮分为高压涡轮和低压涡轮。再热循环不会显著影响热效率的周期,但它不会导致重大的额外工作输出,表示在图中的地区 4-5-6-4' 的图 1-6-4。再热循环要求额外的设备,在重大的投资和使用这类设备必须是从事经济工作增加的输出的 justifled。如果再热不用于避免液滴形成,凝汽器压力必须相当高,这会导致较低循环效率。在这个意义上,再热显著增大时没有再热,但较高的凝汽器压力相比,周期循环效率。

热能与动力工程专业英语-翻译(李瑞扬)1.3 The Characteristics of Fluids 流体的特征constituent:组成的;tangential:切向的;restrain:限制、约束;equilibrium:平衡,均衡;interface:相互关系、分界面;molecule:微小颗粒、分子;continuum:连续体;vessel:容器;tar:焦油、柏油;pitch:树脂;imperceptibly:察觉不到的,细微的;restore:恢复;subside:下沉、沉淀、减退、衰减;hypothetically:假设地、假想地;sphere:球、球体;microvolume:微元体积;rarest:最稀罕的,虽珍贵的A fluid is a substance which may flow; that is, its constituent particles may continuously change their positions relative to one another. Moreover, it offers no lasting resistance tothe displacement, however great, of one layer over another. This means that, if the fluid is at rest, no shear force (that is a force tangential to the surface on which it acts )can exist in it. A solid, on the other hand, can resist a shear force while at rest; the shear force may cause some displacement of one layer over another, but the material does not continue to move indefinitely. In a fluid, however, shear forces are possible only while relative movement between layers is actually taking place. A fluid is further distinguished from a solid in that a given amount of it owes its shape at any particular time to that of a vessel containing it, or to forces which in some way restrain its movement. 流体是可以流动的物质,也就是说,组成流体的质点可以连续的改变它们的相对位置。

(Heat transfer is the science)传热学是一门试图预测热量传递可以发生在温差存在的两个物体之间的科学。

(Thermodynamics teaches that this)热力学告诉我们能量的传递以热量的形式。

传热学不仅可以解释热能怎样被传送,同样可以预测在某种特殊的情况下产生的热交换率。

实际上热交换率的客观分析指出了传热学和热力学之间的差异。

热力学研究对象是处于平衡状态的系统,他可能被用于预测一个系统从一种平衡状态改变到另一种状态所需要的能量的多少,他可能不被用于预测发生在非平衡状态下的系统的热的交换量有多快。

传热学通过提供了可以作为科学中的热力学被用作传热项目基础的实验法则是非常简单的并且容易扩展到各种各样的实际情况当中。

(When a temperature gradient)当温度梯度存在于一个物体中时,经验显示能量将会从高温区域传递到低温区域,我们说能量是通过导热传递并且单位面积的传热效率于法向温度梯度成正比。

(When a fluid at rest or in motion)当流体以不同的温度与一块平板的表面接触且处于静止或运动时据热力学法则规定能量将朝低温区域流动,我们说热量被交换走了并且我们把这个过程称为对流换热过程。

(For both situations shown in fig,1.2)对于表1.2所示的两种情况我们用牛顿冷却定律来表述对流的整体作用。

(The temperature Tw is that)温度Tw是直接与平板表面接触的温度,温度T∞是为了确保平板表面温度不产生明显影响而使流体远离平板表面的所在区域的温度,面积A是与流体接触的表面区域,并且我们应该注意A与热流方向垂直。

比例因子h被叫做传热系数(也是单位面积的导热量或对流换热量)并且取决于几何布置、方向和表面状况(光滑或粗糙)、还有流体的物性和速度。

(There are two convection modes)有两种对流换热模型:强制对流换热和自然对流换热,如果一块被加热的平板暴露一个周围没有额外动因的房子里,空气的流动将经验的被认为是平板附近存在密度梯度的结果,我们称之为自然对流或是无常对流,强制对流与此相反,经验的认为是在风扇吧空气吹到平板上的情况。

在空调系统中,风机所输送的空气包含:室外空气,室内空气(也叫循环空气),室内外混合空气。

The fan pulls air from the outdoors and from the room at the same time. Since the drafts in the room cause discomfort, and poor air movement slows the tody heat rejection process, it is necessary to regulate the amount of air supplied by the fan. To accomplished this regulation, a fan is selected that can deliver the correct amount of air. By controlling the speed of the fan, the air stream in the room can be regulated to provide good circulation without drafts.风机从室外引入空气,同时把室内空气排出,由于室内吹风会产生不舒适,空气稀薄时会减慢热流动过程。

3.1 Heat of CombustionIn a boiler furnace (where no mechanical work is done) the heat energy evolved from the union of combustible elements with oxygen depends on the ultimate products of combustion and not on any intermediate combinations that may occur in reaching the final result.A simple demonstration of this law is the union of 1 lb of carbon with oxygen to produce a specific amount of heat. The union may be in one step to form the gaseous product of combustion, CO2, or under certain conditions the union may be in two steps, first to form CO, producing a much smaller amount of heat and, second the union of the CO so obtained to form CO2, releasing 9755 Btu . However, the sum of the heats released in the two steps equals the 14100 Btu evolved when carbon is burned in one step to form CO2 as the final product.3.1燃烧热在锅炉炉(没有机械的工作是做的)的热能的演变而来的元素与氧结合易燃取决于最终产品的燃烧而不是任何中间组合可以发生在达到最后的结果。

i.e. it is in steady-state.Often we will consider process that change “slowly”-termed quasi-equilibrium or quasi-static process.A process is quasi-equilibrium if the time rate of change of the process is slow relative to the time it takes for the system to reach thermodynamic equilibrium.It is necessary that a system be quasi-equilibrium before applying many of the thermodynamics relations to that system.热力学第一二定律:In simplest terms,the law of thermodynamics dictate the specific for the movement of heat and work.Basically,the First Law of Thermodynamic is a statement of the conservation of energy-the Second Law is a statement about the direction of that conservation-and the Tired Law is a statement about reaching absolute Zero.The first law of thermodynamic is a statement of the principle of conservation of energy.It can also be considered as defining a property,the internal energy.The Second law of Thermodynamic states that in all energy exchanges,if no energy enters or leaves the system,the potential energy of the state will always be less than that of the initial states.This is also commonly referred to as entropy.举例说明热力学定律应用:a cup of hot coffee left on a table eventually cools,but a cup of cool coffee in the same room never gets hot by itself.The high-temperature energy of the coffee is degraded(transformed into a less useful form at a lower temperature)once it is transferred to the surrounding air.An ordinary house is,in some respects,an exhibition hall filled with womders of thermodynamics.Many ordinary household utensils and applicances are designed,in whole or in part,by using the principles of thermodynamics.Some examples include the electric or gas range,the heating and air-condition systems,the refrigerator,the humidifier,the pressure cooker,the water heater,the iron,and even the computer,and the TV.On a large scale,thermodynamics plays a major part in the design and analysis of automotive engines,rockets,jet engine,and conventional or nuclear power plans,solar collectors,and the design of vehicle form ordinary cars to airplanes.绝热系统:isolated systems:not exchangeing heat,matter or work with their environment.开口系统:exchanging energy (heat and work )and matter with their environment .闭口系统:exchangeing energy (heat and work )but not matter with their environment .孤立系统:rigid boundary :not allowing exchange of work .辐射换热:The mechanism in this case is electromagnetic radiation .We shall limit our discussion to electromagnetic radiation which is propagated as a result of a temperature difference ;this is called thermal radiation .对流传热:when a fluid at rest or in motion is in contact with a surface at a temperature different from the plate ,energy flows in the direction of the lower temperature as required by the principle of thermodynamics .we say that heat is convected away ,and we call the process convection heat transfer .对流传热的方式:There are two convection modes :forced convection and natural convection .If a heated plate were exposed to ambient room air without an external source of motion ,a movement of the air would be experienced as a result of the density gradients near the plate .We call this natural ,or free ,convection as opposed to forced convection ,which is experienced in the case of the fan blowing air over a plate .传热学:Heat transfer is the science that seeks to predict the energy transfer that may take place between material bodies as a result of a temperature difference .传热学和热力学的区别:Thermodynamics teaches that this energy transfer is defined as heat .The science of heat transfer seeks not merely to explain how heat energy may be transferred ,but also to predict the rate at which the exchange will take place under certain specified conditions .The fact that a heat -transfer rate is the desired objective of an analysis points out the difference between heat transfer and thermodynamics .Thermodynamics deals with systems in equilibrium ;it may be used to predict the amount of energy required to change a system from one equilibrium state to another ;it may not be used to predict how fast a change will take place since the system is not in equilibrium during the process .Heat transfer supplements the first and second principles of thermodynamics by providing additional experimental rules which may be used to establish energy -transfer rates .As in the science of thermodynamics ,the experimental rules used as a basis of the subject of heat transfer are rather simple and easily expanded to encompass a variety of practical situations .影响辐射传热的因素:To take account of the “gray” nature of such surface we introduce another factor into热能与动力工程thermal energy and power engineering能量转化energy-transfer比例常数proportionality

“slowly”-termed quasi-equilibrium or quasi-static process.A process is quasi-equilibrium if the time rate of change of the process is slow relative to the time it takes for the system to reach thermodynamic equilibrium.It is necessary that a system be quasi-equilibrium before applying many of the thermodynamics relations to that system.热力学第一二定律:In simplest terms,the law of thermodynamics dictate the specific for the movement of heat and work.Basically,the First Law of Thermodynamic is a statement of the conservation of energy-the Second Law is a statement about the direction of that conservation-and the Tired Law is a statement about reaching absolute Zero.The first law of thermodynamic is a statement of the principle of conservation of energy.It can also be considered as defining a property,the internal energy.The Second law of Thermodynamic states that in all energy exchanges,if no energy enters or leaves the system,the potential energy of the state will always be less than that of the initial states.This is also commonly referred to as entropy.举例说明热力学定律应用:a cup of hot coffee left on a table eventually cools,but a cup of cool coffee in the same room never gets hot by itself.The high-temperature energy of the coffee is degraded(transformed into a less useful form at a lower temperature)once it is transferred to the surrounding air.An ordinary house is,in some respects,an exhibition hall filled with womders of thermodynamics.Many ordinary household utensils and applicances are designed,in whole or in part,by using the principles of thermodynamics.Some examples include the electric or gas range,the heating and air-condition systems,the refrigerator,the humidifier,the pressure cooker,the water heater,the iron,and even the computer,and the TV.On a large scale,thermodynamics plays a major part in the design and analysis of automotive engines,rockets,jet engine,and conventional or nuclear power plans,solar collectors,and the design of vehicle form ordinary cars to airplanes.绝热系统:isolated systems:not exchangeing heat,matter or work with their environment.开口系统:exchanging energy (heat and work )and matter with their environment .闭口系统:exchangeing energy (heat and work )but not matter with their environment .孤立系统:rigid boundary :not allowing exchange of work .辐射换热:The mechanism in this case is electromagnetic radiation .We shall limit our discussion to electromagnetic radiation which is propagated as a result of a temperature difference ;this is called thermal radiation .对流传热:when a fluid at rest or in motion is in contact with a surface at a temperature different from the plate ,energy flows in the direction of the lower temperature as required by the principle of thermodynamics .we say that heat is convected away ,and we call the process convection heat transfer .对流传热的方式:There are two convection modes :forced convection and natural convection .If a heated plate were exposed to ambient room air without an external source of motion ,a movement of the air would be experienced as a result of the density gradients near the plate .We call this natural ,or free ,convection as opposed to forced convection ,which is experienced in the case of the fan blowing air over a plate .传热学:Heat transfer is the science that seeks to predict the energy transfer that may take place between material bodies as a result of a temperature difference .传热学和热力学的区别:Thermodynamics teaches that this energy transfer is defined as heat .The science of heat transfer seeks not merely to explain how heat energy may be transferred ,but also to predict the rate at which the exchange will take place under certain specified conditions .The fact that a heat -transfer rate is the desired objective of an analysis points out the difference between heat transfer and thermodynamics .Thermodynamics deals with systems in equilibrium ;it may be used to predict the amount of energy required to change a system from one equilibrium state to another ;it may not be used to predict how fast a change will take place since the system is not in equilibrium during the process .Heat transfer supplements the first and second principles of thermodynamics by providing additional experimental rules which may be used to establish energy -transfer rates .As in the science of thermodynamics ,the experimental rules used as a basis of the subject of heat transfer are rather simple and easily expanded to encompass a variety of practical situations .影响辐射传热的因素:To take account of the “gray” nature of such surface we introduce

静态型再生热交换器基本上是一种多孔物质,具有大的蓄热能力,例如陶瓷丝网。

热流体和冷流体在热流体流动期间流向再生器的基体,并且在冷流体
流动期间从基体流向冷流体。

因此,该基质用作临时蓄热介质。

动态型再生器包括一个旋转的滚筒和通过滚筒不同部分的热流体和冷流体的连续流动,使得滚筒的任何部分周期性地通过热流体教材15页流,储存热量,然后通过冷流,排出储存的热量。

再一次,滚筒充当将热量从热流体流传输到冷流体流的介质。

另一类冷、热流体交替通过同一流动面积的换热器为蓄热式换热器。

静态型蓄热式换热器基本上由多孔介质组成,其热容量大,如陶瓷铁丝网。

冷、热流体交替地流经这些多孔介质,热量先由流过的高温流体传递到换热器的换热基体,再由基体传递给接着流过的低温流体。

因此,基质充当临时蓄热介质。

该动态蓄热式热交换器内部设置有转鼓,冷、热流体连续流过转鼓的不同部位,使转鼓的任何部位周期性地通过热流体蓄热,然后通过冷流体释放蓄热。

滚筒作为热流体向冷流体传热的介质。

热交换器通常被赋予特定的名称,以反映它们的具体应用。

例如,冷凝器是一种热交换器,其中一种流体在流经热交换器时被冷却和冷凝。

锅炉是另一种热交换器。

教材中长达16页的热交换器通常被赋予特定的名称,以反映其特定的用途。

例如,冷凝器是一种热交换器,当流体流动时,通过它发生冷却冷凝。

锅炉是另一种热交换器,流体在其中吸收热量并蒸发。

空间散热器是一种将热流体的热量辐射到周围空间的热交换器。
