Dieterici气体的焦汤系数研究

Joule Thomson Coefficient of Dieterici Gas

以Dieterici气体为工质,应用Dieterici气体方程以及热力学基本理论,推导出Dieterici气体焦汤系数的解析表达式,应用实例计算了焦汤系数的具体数据,并与Redlich-Kwong气体方程导得的焦汤系数进行比较.结果表明,二者在低温下的计算结果几乎重合,对低温制冷具有一定的实际意义.

This study made a brief analysis of the Dieterici gas,Dieterici gas as working fluid, the application of Dieterici gas equation and the basic thermodynamic theory, analytic formula derived Dieterici gas Joule Thomson coefficient, applied specific data calculation of Joule Thomson coeffi- cient,and compared Redlich-Kwong equation of gas coke soup coefficient. The results showed that, both calculation results at low temperatures seemed to be almost coincide,and were of practical sig- nificance for the low temperature refrigeration.
