Abstract

A computational expression is given from which one may calculate the final temperature in the polytropic compression of any real gas. The method is based on the Peng-Robinson equation of state and the entropy-temperature rate procedure. The results we obtained are compared with those derived from the pressure-volume exponent method. We show that the latter method fails at gas densities above about 0.6ï²c, while the former continues to give good results up to the highest density considered in this work, which is 1.5ï²c.Keywords: Peng-Robinson equation of state, polytropic compression, entropy-temperature rate method, polytropic exponent methods
