The paper describes the implementation of a modified state equation for perfect gas and Tammann equation into a 3D rans solver FlowER. In the modification the specific heats are assumed as linear functions of temperature. A 5-stage LP (low pressure) steam turbine is calculated, and the comparison of results for constant and variable specific heats is illustrated. The modification significantly improves the correctness of determination of thermodynamic parameters in the entire flow region, especially in the exit stage.
