Abstract

Variable geometry turbine can boost the performances of engine in a wide range of working conditions especially at low speeds. When the turbine expansion ratio is large and the nozzle opening is small, a shock wave is generated near the trailing edge of the nozzle blade. Weakening the shock wave at the trailing edge of nozzle blade is a key task. In this study, a new coupling optimization method of the nozzle blade to control trailing edge shock wave is proposed. Firstly, a parametric modeling method of the nozzle blade that includes both global profile and local bulge designs is constructed. Then the quantitative evaluation methods of shock wave intensity and aerodynamic loss are defined. Finally, the shock wave control of the turbine nozzle based on the global profile and local bulge coupling optimization is implemented. The results at the design condition show that the shock wave intensity of the nozzle is decreased by 71.7 %, the total pressure loss is reduced by 25.8 %, the turbine adiabatic efficiency is increased by 3.59 %, and the variation of mass flow rate does not exceed 4 %. The results analyses at off-design conditions show that the coupling optimization has good robustness and can be generalized.
