| 英文摘要 | A new type of film cooling hole with micro groove structure is presented in this paper. Based on the finite volume method and the Realizablek-epsilon model, the film cooling process of the hole in a flat plate structure is simulated. The surface temperature distribution and film cooling effect of different film cooling holes were analyzed. The effects of micro-groove structure on wall attachment and cooling efficiency of jet were discussed. The results show that under the same conditions, the transverse coverage width and overall protective area of the new micro-groove holes are larger than those of the ordinary cylindrical holes and special-shaped holes. Compared with ordinary holes, the new micro-groove holes can better form the film covering on the surface and enhance the overall film cooling efficiency of the wall. For example, when the blowing ratioM=1.5, the effective coverage ratio of micro-groove holes is 1.5 times the dustpan holes and is 8 times the traditional cylindrical holes. It provides reference data and experience rules for the optimization and selection of advanced cooling structure of high performance aero-gas engine hot-end components. |
