- Abstract
In order to study the film cooling effectiveness of blade trailing edge, three kinds of trailing edges are designed, and the experimental system is built. The adiabatic cooling effectiveness of trail edges is studied by infrared cameras. The experimental result shows that the cooling effectiveness of the three kinds of trailing edges are different. There is a max film cooling effectiveness value of the test piece I , and the point where the maxmum comes is moving away from the exit when the blowing ratio increases. The film cooling effectiveness of test pieces I and II both gradually decrease along the surface of trailing edge. At the same point of the surface of trailing edge, the cooling effectiveness of test piece I is better than those of other two test pieces. Therefore the configuration of test piece III is suitable for the design of turbine blade trailing edge.
