摘要：
In this study, we present an analytical expression to evaluate the speed of sound and heat capacities of refrigerant gases using the second virial coefficient over the Stockmayer potential. The obtained analytical formula yields the accurate and fast evaluation of speed of sound and heat capacities of refrigerant gases. The performance of the suggested approach is verified by its application to the speed of sound and heat capacities calculations of refrigerant gases for R134a, R152a, R718, R32 and R717 in comprehensive range of pressure and temperature. We have also demonstrated that the Stockmayer potential has to be taken into account in the calculations during the evaluation of speed of sound and heat capacities. The obtained results agree well with experimental and theoretical results in the literature.
