摘要

与以往的湍流模型不同

GAO-YONG不可压湍流控制方程组不需要任何经验系数及壁面函数。其级数形式的能量方程与非线性现象多尺度层次相对应

具备了描述湍流统计平均和拟序结构的双重功能。本文采用交错网格和SIMPLE方法求解GAO-YONG不可压湍流方程组

考察了GAO-YONG方程组中能量方程阶数以及计算网格对拟序结构的影响

证明了该方程在描述拟序结构方面具有一定的适定性。

Abstract

Unlike widely used turbulence models

the GAO-YONG model equations use no empirical coefficients or wall functions. And series form of energy equation corresponds to the scales of nonlinearity. In this paper

two-dimensional

incompressible turbulent boundary layer with zero pressure gradient is numerically simulated with GAO-YONG turbulence model. Employing staggered grid arrangement

an incompressible SIMPLE code is used. The calculation successfully simulates the coherent structures in the turbulent boundary layer and the effect of the order of the energy equation and grid scales on the coherent structures. All the results verify the adaptability of the equations to real intermittent turbulent flow.
