摩尔体积、压缩因子、剩余熵、剩余焓与逸度等的计算是流体热力学性质计算的重要内容,在化工热力学课程中要用较多的课时讲授,而这些计算往往比较复杂,经常涉及试差计算与迭代计算,又经常要进行针对不同流体的相同内容的计算,使得计算异常繁杂,课堂内难于讲授清楚。本文介绍了微软电子表格Excel在流体热力学性质计算中的应用。该计算简单明了,且不易出错,便于课堂内知识传授,是一种值得推广的教学与实用计算方法。

The mole volume, compressibility factor, residual enthalpy, residual entropy and fugacity calculations are the most important contents in the calculation of thermodynamic properties of fluids, which take many teaching hours in the course of Chemical Engineering thermodynamics. The calculations are generally complicated, involving trial and error calculations and iterative calculations. Frequently, the same calculations are repeated for different fluids, resulting in an arduous job. Here we introduce a meth- od for above calculations. Microsoft Excel is used for the calculations. The calculations with Excel are simple and clear, not easy to be wrong, and feasible for illustration in the class. It is a method worthy of being recommended to solve problems in both engineering and class.
