The wall function is one of approaches to treatsolid boundaries in turbulent flow analysis using the κ-ε model. The conventional one is based on the logarithmic law. The analytical wall function proposed by Craft et al. is not based on the logarithmic law. The feature of the analytical wall function is that the effects of the convective transport and the pressure gradient are reflected. In the present study, the analytical wall function is developed by the finite elementmethod and employed to a channel flow and a flow over a backward step. As a result, the analytical wall function effects the backflow in the region modeled by the wall function.
