CFD Online 网站中关于y+的定义如下：A non-dimensional wall distance for a wall-bounded flow can ...
如果y表示流体介质距离壁面的真实垂向距离,SI单位为m;那么y+则表示以某种方式对y进行归一化处理后,得到的一个无量纲的参数。CFD Online 网站中关于y+的定义如下:A non-dimensional wall distance for a wall-bounded flow can be defined in the following way: ...
(1)pointwise的y+计算工具网址为/yplus/,打开后如下图所示,输入速度、密度、粘度、特征尺寸以及Y+,网页会计算出第一层网格高度与雷诺数。 (2)CFD-Online的计算工具网址为/Tools/yplus.php,打开后如下图所示。 6、遗留的问题 这里谈的第一层网格间距估计是在输入已知Y+的情况下获得的,实际上在计算完后还需...
