On the Evaluation of van der Waals and Dieterici Models Using the Calculation of Virial Coefficients of Refrigerants

In this research, we calculate second and third virial coefficients of some refrigerants like R123,R124, R143a and R152a in order to evaluate the performance of van der Waals and Dieterici modelsof equations of state (EOSs). The investigated EOSs based van der Waals type consist of van derWaals (vdW), Redlich-Kwong (RK), Peng-Robinson (PR), Soave-Redlich-Kwong (SRK). The EOSsbased Dieterici model evaluated in this research consist of Dieterici (D) and Dieterici-Carnahan-Starling (DCS).
