本文依据文献［１］给出的烃燃气热力性质计算方法，计算了热力学状态参数。在计算气动参数时，引入不可逆的概念。编写了求解燃气热力学参数的通用程序。程序适用于燃料系数β从０到１；温度从２００Ｋ到１８００Ｋ范围的任意碳氢比的烃燃料燃烧后生成的燃气。气动参数的结果与文献［２］多比热结果进行了比较，其差别在０．１％以内。计算程序求解合理而且方便，可在工程设计中应用。
In this paper, thermodynamic parameters are calculated based on the calculation of thermodynamic properties of hydrocarbon gas given in [1]. In the calculation of aerodynamic parameters, the introduction of the concept of irreversibility. A general procedure for solving gas thermodynamic parameters has been written. The program is applicable to gas produced after the combustion of a hydrocarbon fuel of any hydrocarbon ratio with a fuel factor β from 0 to 1 and a temperature in the range of 200K to 1800K. The results of the aerodynamic parameters are compared with those of the literature [2], and the differences are less than 0.1%. The calculation procedure is reasonable and convenient and can be applied in engineering design.
