• B-14 Performance Prediction of Partial Admission Stage based on Simulation of Unsteady Three-Dimensional Flows

抄録

In this paper, the performance of a partial admission stage is parametrically predicted using the high-order high-resolution numerical method developed by our group. Compressible Navier-Stokes equations are solved by the 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. The SST-model is also solved for evaluating the eddy-viscosity. Unsteady three-dimensional flows through half-arc nozzle-rotor cascade channels considering a partial admission are numerically investigated. 54 nozzle passages with two blockages and 30 rotor passages are simultaneously calculated. The influence of the flange in the nozzle box to the lift of rotors is predicted.
