【 摘 要 】

The cooling effectiveness of combustor transition pieces increases significantly in accordance with turbine temperature. In this issue, we create a scenario in which using three-dimensional computational to predict the performance of film cooling model with three rows holes and double chambers on the flat surface that the model could simulate the TP?s structure and performance. Fluent, a commercial CFD software, is extensively used in the current work for numerical simulations. A comprehensive study is performed on the effect of coolant injection angles on film cooling. The the temperature distribution in the inner wall, cooling effectiveness, and the velocity distribution of coolant flow with different cases is compared. Analysis on flow injection orientations is beneficial to enhance the turbine inlet temperature and improve gas turbine efficiency
