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