冲击-发散冷却火焰筒浮动瓦片三维壁温计算分析

Numerical analysis of 3D temperature field of an impingement-effusion cooled flame tube floating tile

论述了采用冲击-发散冷却技术的火焰筒浮动瓦片的传热计算分析方法,以及传热数学模型和边界条件处理.并采用ANSYS程序的热分析模块对浮动瓦片的三维壁温场进行了计算.计算结果与试验结果进行了对比分析,两者有较好的吻合性,计算值与试验值的相对误差不大于6%.

Heat transfer numerical analysis methods, maths model, and boundary condition treatment for an impingement-effusion cooled flame tube floating tile are discussed in the paper. By using the heat analysis module of ANSYS code, the 3D temperature field of the floating tile was calculated. The numerical results showed that the agreement with the test data is fairly good. The relative error between numerical results and test data is not greater than 6%
