Оптимизация ступеней газовых турбин с использованием 3D моделей расчета течения

Abstract

The approach of aerodynamic optimisation of a turbine blade 3D shape using the 3D flow computation model is described. The optimisation technique consists in direct methods of a local search and heuristic ones of a global search as well as their hybridisation. Results of the optimisation studies are presented for the gas turbine flowpath. The computational results demonstrate improved flow behaviour, reduced kinetic energy losses and increased turbine efficiency.
