(火积)损失是热力学过程中系统(火积)的减少量,它等于流入系统的(火积)流与流出系统的(火积)流之差,也等于(火积)耗散和功(火积)之和。对于传热过程,(火积)损失即为(火积)耗散,为(火积)损失的不可逆部分,反映了热力学第二定律。对于卡诺循环,(火积)损失即为功(火积),具有可逆特性,体现了热力学第一定律。对于包括传热过程和热功转换过程的系统,(火积)损失即包括(火积)耗散也包含功(火积)。(火积)损失的各个组成部分可以通过以热流和温度为横、纵坐标的T-q图上的面积描述。(火积)损失可应用于包含热功转换的过程以优化系统输出功,算例表明在一定条件下最大输出功率和最大(火积)损失率相对应。
(Fire Product) loss is the reduction of the system (fire product) in the thermodynamic process, which is equal to the difference between the (fire product) flow of the inflow system and the (fire product) flow out of the system, (Fire product) sum. For the heat transfer process, (fire product) loss is (fire product) dissipation, as (irreversible part of the loss of fire product), reflecting the second law of thermodynamics. For the Carnot cycle, (fire product) loss is the work (fire product), with reversible properties, reflecting the first law of thermodynamics. For systems that include the heat transfer process and the heat transfer process, the loss of (ie, implosion) includes the product of (fire product) dissipation and work (fire product). The components of the (fire product) loss can be described by the area on the T-q plot with heat flux and temperature in horizontal and vertical coordinates. (Fire product) loss can be applied to the process including the conversion of thermal power to optimize the output power of the system. The example shows that under certain conditions, the maximum output power and the maximum (fire product) loss rate correspond to each other.
