Redlich kwong model

WebIn physics and thermodynamics, the Redlich–Kwong equation of state is an empirical, algebraic equation that relates temperature, pressure, and volume of gases. It is generally more accurate than the van der Waals equation and the ideal gas equation at temperatures above the critical temperature. WebList of implemented real-fluid models in the new libary Modified Soave-Redlich-Kwong (SRK) model for equation of state [1, 2]. Peng-Robinson (PR) model for equation of state [3] JANAF-based model for real-fluid thermodynamic properties. Chung's model (1988) for dynamic viscosity and thermal conductivity [4].
