抄録

In this study, transonic humid-air and wet-steam turbulent flows through a steam turbine cascade channel are calculated. Transonic condensate flows in turbomachinery are numerically predicted by using the high-resolution method developed by our group. Fundamental equations consist of conservation laws of mixed gas, water vapor, water liquid, and the number density of water droplets, coupled with the momentum equations and the energy equation. The classical condensation theory is employed for modeling homogeneous nucleation and non-equilibrium condensation. These equations are solved by a high-order high-resolution finite-difference method based on the fourth-order compact MUSCL TVD scheme, Roe's approximate Riemann solver, and the LU-SGS scheme. SST model is used for evaluating eddy-viscosity.
