主　　题：Jet impingement Curved surface RAST one-equation model Large eddy simulation Heat transfer 

摘      要：The heat transfer and flow characteristics of air jet impingement on a curved surface are investigated with computational fluid dynamics(CFD)*** first applied model is a one-equation SGS model for large eddy simulation(LES)and the second one is the SST-SAS hybrid *** models are utilized to study the flow physics in impinging process on a curved surface for different jet-to-surface(h/B)distances at two Reynolds numbers namely,2960 and 4740 based on the jet exit velocity(U_e)and the hydraulic diameter(2B).The predictions are compared with the experimental data in the literature and also the results from RANS k-ε*** show that both models can produce relatively good ***,one-equation model(OEM)produced more accurate results especially at impingement region at lower jet-to-surface *** terms of heat transfer,the OEM also predicted better at different jet-to-surface *** is also observed that both models show similar performance at higher h/B ratios.
