Numerical Analysis and Study on the Cooling Efficiency of V-shaped Gas Film Holes
The numerical simulation method was used to study the film cooling efficiency of V-shaped film holes under different angles and blowing ratios,and compared with elliptical film holes.The results show that under the same blowing ratio,the cooling efficiency of the three types of V-shaped film holes is higher than that of the elliptical film holes,and the angle has a significant impact on the cooling efficiency of the V-shaped film holes.The calculation results have certain guiding significance for the current design of turbine blade film holes.
