Evaluation of the Performance of the Equations of State Available in CFTurbo for Air
Authors: , ,
Abstract: In this publication, we evaluate the performance of equations of state Perfect Gas, Redlich-Kwong, Aungier/ Redlich-Kwong, Soave/ Redlich-Kwong, Peng-Robinson, and Cool Prop in calculating the properties of air at temperatures between 250 K to 800_K and pressure between 1 bar to 250 bar. Firstly, we research the available literature to find the real density (or molar volume or specific volume) at each point. Then we create these equations and use the temperature and density (or molar volume or specific volume) to calculate the pressure, which is then compared to the pressure of the real values. This comparison evaluates the performance of each equation. Finally, we compare our calculations with online calculators to verify our results and comment on the performance of each equation.
