In this paper, a Soave-Redlich-Kwong adiabatic equation of real gas charged in accumulators is proposed. The Soave-Redlich-Kwong equation is the most accurate real gas model for representing accumulator behavior, but it is relatively complex mathematical equation. For simulating accumulator dynamic behavior, it has been used by combining with a thermal time constant model. The mathematical procedure for the Soave-Redlich-Kwong equation for the adiabatic equation is described in this paper. The Soave-Redlich-Kwong adiabatic equation is discussed by comparing the van der Waals adiabatic equation. By comparing representative gas models, the Soave-Redlich-Kwong adiabatic equation is found to be valid.
