Fluid/solid conjugated heat transfer numerical computation was conducted to study impingement+identical flow convection+film composite cooling by using Fluent 6.3

and the trend of wall temperature field and the cooling effect were obtained

and then the computational results were compared with the testing results.The results indicate that the wall temperature distribution of the composite cooling is well-proportioned

and the cooling effect is better.The numerical results are in good agreement with the testing results

with their maximal relative error of 3.6%.
