摘要

Abstract

The heat transfer and flow characteristics of air jet impingement on a curved surface are investigated with computational fluid dynamics (CFD) approach. The first applied model is a one-equation SGS model for large eddy simulation (LES) and the second one is the SST-SAS hybrid RANS-LES. These 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

) and the hydraulic diameter (2B). The predictions are compared with the experimental data in the literature and also the results from RANS k-ε model. Comparisons show that both models can produce relatively good results. However

one-equation model (OEM) produced more accurate results especially at impingement region at lower jet-to-surface distances. In terms of heat transfer

the OEM also predicted better at different jet-to-surface spacings. It is also observed that both models show similar performance at higher h/B ratios.
