摘要

我们已经实现了一个可视化工具，用于演示非理想卡诺热机，在有限时间内运行。循环时间可以通过滑动条来改变，压力-体积、温度-熵、功率-时间和效率-时间图表会交互变化，并显示在一个屏幕上。我们在大学的热力学入门课程中对可视化工具进行了评估，并对评估结果进行了回顾和讨论。

Pedagogical Visualization of a Nonideal Carnot Engine

We have implemented a visualization tool for the demonstration of a nonideal Carnot engine, operating at finite time. The cycle time can be varied using a slide bar and the pressure-volume, temperature-entropy, power-time, and efficiency-time diagrams change interactively and are shown on one screen. We have evaluated the visualization tool among engineering students at university level during an introductory course on thermodynamics and we review and discuss the outcome of the evaluation.
