In this study, four types of super highly loaded turbine blades are analyzed by a numerical method for the two-dimensional incompressible viscous flow. The governing equations employ the standard κ-ε model are solved in the physical component tensor form with a boundary-fitted coordinate system. The geometries of super highly loaded blades posses the limiting turning angles of about 160 degrees. The pressure distributions on the blade surfaces are compared for four turbine cascades. As the results, it is found that the pressure distribution on the blade surface strongly depend on the blade configuration. |
