计算$p-V$图热力循环热效率的一般形式

General formalism for calculating the thermal efficiency of thermodynamic cycles defined in a $p-V$ diagram

Viktor Könye, József Cserti

摘要:

本文提出了一种计算压力-容积($p-V$)图中任意热力循环热效率的通用方法。为了证明我们的方法是多么有效,我们计算了理想气体发动机的热效率为几个非平凡的循环中的$p-V$图,包括圆形,心形,摆线的Ceva,和星形曲线。我们确定沿循环的段,其中热量从热机吸收或释放。我们的方法可以应用于任何气体模型,作为一个例子,我们提出的范德华气体的结果。

英文摘要:

We develop a general method for calculating the thermal efficiency of arbitrary thermodynamic cycles defined in the pressure-volume ($p-V$) diagram. To demonstrate how effective our approach is, we calculate the thermal efficiency of ideal gas engines for a few non-trivial cycles in the $p-V$ diagram, including a circular shape, a heart shape, a cycloid of Ceva, and a star-shaped curve. We determine the segments along the cycle where heat is absorbed or released from the heat engine. Our method can be applied to any gas model, and, as an example, we present the results for the van der Waals gas.
