摘要：Experimental studies were carried out on the film cooling of the composite plates formatted through different weaving modes. An infrared radiation camera was used to capture the temperature distributions on hot side wall, and the effects of thermal conductivity, blowing ratio, and mainstream temperature on the overall cooling effectiveness were analyzed. Numerical simulations on the anisotropic composite plates with a single film hole were further conducted to explore the individual influence of thermal conductivity along the X, Y, and Z directions on the wall temperature distribution as well as the overall cooling effectiveness. Results show that the film cooling effectiveness increases with the enhancement of the blowing ratio and decreases with the increase of the main stream temperature. Among the three anisotropic composite plates, 2.5D composite plate produces the highest film cooling effectiveness while 3D composite plate gives the lowest cooling effectiveness. The increase of thermal conductivity along X and Z directions can improve the film cooling efficiency while the increase of thermal conductivity along Y direction has little influence on the film cooling efficiency. © 2017, Editorial Department of Journal of Aerospace Power.
