Effect of location of penny platform in variable stator vane on endwall flow

  • Through experiment and numerical simulation of simplified variable stator vane(VSV) model,the effect of different penny platform locations on the flow in endwall region was studied.The results show that there are two factors affect the loss of endwall flow:the leakage cause by aerodynamic loading and the mixing of flow around the penny platform.Optimization of the location and size of the penny platform which aims at covering the front end of the aerofoil can decrease the leakage and flow loss,thus aerodynamic performance would be improved.
