摘要
Conjugate calculation methodology is used to simulate the C3X gas turbine vanes cooled with leading edge films of 'shower- head' type. By comparing calculated results of different turbulence models with the measured data, it is clear that calculation with the transition model can better simulate the flow and heat transfer in the boundary layers with leading edge film cooling. In the laminar boundary layers, on the upstream suction side, the film cooling flow presents 3D turbulent characteristics before tran...
