摘要

我们使用OpnFoampackage对波浪形表面上的湍流流动进行了数值研究，研究了不同波浪形表面上通道壁扰动的振幅和波长。RANS和LES模型用于描述湍流特性。流动中的雷诺数为20000。得到了通道壁上速度和剪应力的平均分布。计算了各种通道几何参数下剪切应力扰动的幅值和相移值。并与理论模型和实验结果进行了比较。

Numerical Simulation of a Turbulent Gas Flow over a Wavy Surface

We use the OpnFoam package to numerically study the turbulent flow over a wavy surface for various values of the amplitude and wavelength of the perturbation of the channel wall. The RANS and LES models are used to describe turbulent characteristics. The Reynolds number in the flow is 20 000. The average profiles of velocities and shear stresses on the channel wall are obtained. The values of the amplitude and phase shift for perturbations of the shear stress are calculated for various geometrical parameters of the channel. Comparison with the theoretical model and experimental results is carried out.
