A Comparison of Low Reynolds Number k Models

Low Reynolds number k-ε turbulence model is gained by modifying the standard k-ε turbulence model, it applies to the whole fluid region.This case was studied six low Reynolds number k-ε turbulence model and standard k-ε turbulence model in FLUENT14.0for numerical calculations near-wall shear flow,through comparing the speed, thus it is concluded that low Reynolds number k-ε turbulence model is more accurate than the standard k-ε turbulence model.In the low Reynolds number k-ε turbulence model, LS, YS model compared to several other model, calculated value and actual value deviation is bigger.
