Algebraic explicit wall models are proposed to cover the entire inner region of the turbulent boundary layer, reducing the computational effort for large eddy simulation of wall-bounded turbulent flows. The models use closed-form formulas with logarithmic- or power-function-based laws of the wall to straightforwardly evaluate the friction velocity on near wall grids, demonstrating good performance in wall modeled large eddy simulation of turbulent plane channel flow.
Algebraic explicit wall models covering the entire inner region of the turbulent boundary layer are proposed to reduce the computational effort for large eddy simulation of wall-bounded turbulent flows. The proposed formulas are given in closed forms with either logarithmic- or power-function-based laws of the wall, allowing straightforward evaluation of the friction velocity on near wall grids independent of their locations in the turbulent boundary layer. The performance of the proposed models is demonstrated by the wall modeled large eddy simulation of a turbulent plane channel flow.
