A time-marching methods for calculation of the water vapor flows

A two-dimensional Euler code is developed for predicting the flowfield of water vapor in turbomachinery channels. The empirical equation of state given by Rivkin and Kreinenevskaya (1967) is chosen for estimating the water vapor properties. The governing equations are discretized by the cell-centered finite volume formulation. The numerical procedure is based on an explicit Godunov-type scheme using the exact Riemann solver for the real gas.
