| Abstract: | Optimization on the turbine transition section(TTS) between the high pressure turbine (HPT) and the low pressure turbine(LPT) in a mid-power gas turbine was conducted by CFD method.Based on original TTS and load struct,the inlet guide vane(IGV) and the TTS were newly designed on the Design3D,an optimization platform belong to Numeca software.The results of numerical simulation show that the aerodynamic performance of the newly designed TTS can fully satisfy with the design indices.Because the flow field in ... |
