Y+计算采用PointWise官方网页提供的计算方法。见网址 http://www.pointwise.com/yplus/ 。该方法基于 Frank M. White's Fluid Mechanics 5th edition, page 467中关于平板边界层理论计算。 具体计算方法为: 先计算雷诺数: 通过雷诺数计算摩擦系数: 计算壁面剪切力: 计算: 得到第一层网格高度: 2 程序代码 创建...
Y+ Wall Distance Estimation Input Freestream velocity:[m/s] Density:[kg/m3] Dynamic viscosity:[kg/ms] Boundary layer length:[m] Desired Y+ value:[] Output Reynolds number:[] Estimated wall distance:[m]
Improve CFD Accuracy with Correct Mesh Resolution It's important that your mesh near the wall is properly sized to ensure accurate simulation of the flowfield. This calculator computes the height of the first mesh cell off the wall required to achieve a desired Y+ using flat-plate boundary...
Re: Y - PLUS #6 M Patel Guest Posts: n/a Hi, thanks for your very informative reply. I already understand the velocity profiles near and away from the wall. However, I am still confused about how I can modify the y-plus values near the wall, are they mesh dependent?
