摘要
运用对比态形式的Redlich-Kwong(R-K)状态方程,分析和导出J-T效应的对比转换温度关系式。并且通过Matlab仿真技术绘制出vdw、Berthelot、Dieteric和R-K状态方程气体的对比转换曲线,将其与Gunn.Chueh-Prausnitz方程进行对比分析,从中可以看出R-K方程在描述气体的对比转换温度、对比转换压强的特征值以及对比转换曲线方面,优于vdw、Berthelot和Dieteric等状态方程。能很好的反映气体J-T效应的对比转换温度和对比转换曲线的性质。
The contrast- state forms of Redlich- Kwong（ RK） equation of state were used,and JT transition temperature contrast effect relationship was analyzed and exported. Contrast conversion curves of vdw,Berthelot,Dieteric and RK equations of state of gas were draw through Matlab simulation,which were compared with Gunn. Chueh-Prausnitz equation can be seen better than vdw,Berthelot and Dieteric,etc.,from the equation describing gas RK contrast transition temperature,contrast eigenvalues and comparative aspects of the conversion curve converted pressure equation of state. It can well reflect the comparative effect of converting nature JT gas temperature and contrast conversion curve.
