大家好,本人在学习twoPhaseEulerFoam pEqn.H 代码时发现,code中定义的pressure "diffusivity"
"rAUf", mag(alphaf1*alpharAUf1 + alphaf2*alpharAUf2)
alpharAUf1在UEqn.H中给出了定义:
fvc::interpolate(max(alpha1, phase1.residualAlpha())*rAU1)
与公式中给出的形式并不一样(下图右边项),
这是代码出现的bug还是我理解的不到位?还请大佬们解惑
@李东岳 现在这个问题还没有搞清楚,东岳大佬能否帮忙解答一下?
跟下面这个一致么
\begin{equation}\label{incompressiblep} \nabla\cdot\left(\left(\alpha_{\rd,\rP}\frac{\alpha_{\rd,\rP}}{A_{\rd,\rP}}+\alpha_{\rd,\rP}\frac{\alpha_{\rd,\rP}}{A_{\rd,\rP}} \right)\nabla p_{\mathrm{rgh},\rP}\right), \end{equation}
@李东岳 一致,但是我实在看不出来是怎么推出来的这个形式。 我是看的这个网站上的推导http://xiaopingqiu.github.io/2015/05/17/twoPhaseEulerFoam2/ 请问李老师您这个公式有相应的文献或者网站吗?万分感谢!困扰好久了

@李东岳 感谢大佬!我好好研读一下
