| Abstract: | Based on non-uniform rational B-spline surface technique,the parameterized geometry profiling of non-axisymmetric endwall for turbine cascades was achieved in this paper.An aerodynamic optimization system for non-axisymmetric endwall profiling was also constructed by using iSIGHT~(TM) commercial software as optimization platform and NUMECA software for numerical simulation.This optimization system was apphed to the stator hub design of a turbine stage.The results show that pressure field near non-axisymmetric endwall can be changed and the aerodynamic performance of the turbine cascade can be improved. |
| Keywords: | non-axisymmetric endwall NURBS surface optimal design |
