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.

用于大涡模拟的显式壁模型

提出了覆盖湍流边界层整个内部区域的代数显式壁模型，以减少壁边界湍流的大涡模拟的计算量。所提议的公式以封闭形式给出，具有基于对数或基于幂函数的壁定律，从而可以直接评估近壁网格上的摩擦速度，而无需考虑其在湍流边界层中的位置。拟议模型的性能通过湍流平面通道流动的壁面模拟大涡模拟得到证明。
