Numerical Simulation of the 3D Viscous Flow in the Exhaust Casing of a Low-Pressure Steam Turbine
Keyword(s):
Numerical results of the 3D viscous flow in a downward exhaust casing of a low-pressure steam turbine, obtained with the 3D Navier-Stokes solver Fine/TURBO, is presented. Comprehensive comparisons of the computational results with the available experimental data, such as velocity, static and total pressure coefficients, are given. A good agreement with the experimental data is obtained. The computational results reveal a complex vortex system, including a passage vortex, a secondary vortex, an endwall vortex and a separation vortex, within the casing model. It is found that of all the vortices, most portion of energy losses within the casing is contributed from the passage vortex.
