Abstract
Unsteady wet-steam flows through a three-stage low-pressure steam-turbine model developed by Mitsubishi Heavy Industry are numerically investigated. We solved compressible Nervier-Stokes equations coupled with nonequilibrium condensation models and SST turbulence model. Numerical results obtained by assuming single passage and multi passage are compared with each other and the effect of the blade number on unsteady wet-steam flows in the real low-pressure steam turbine is discussed. Numerical results are also compared with the experimental data.
