多相流射流求解
-
各位大佬好,我最近正在用compressibleInterFoam计算射流问题,求解出来的相体积分数分布如下:
感觉分布不是很正常。
我的fvScheme设置如下:对流项和扩散项: div(phi,alpha) Gauss vanLeer; div(phirb,alpha) Gauss linear; div(rhoPhi,U) Gauss linearUpwindV grad(U); div(rhoPhi,T) Gauss linearUpwind grad(T); div(phi,p) bounded Gauss Gamma 0.2; div(rhoPhi,K) bounded Gauss Gamma 0.2; div(phi,k) bounded Gauss Gamma 0.2; div(phid1,p_rgh) bounded Gauss Gamma 0.2; div(phid2,p_rgh) bounded Gauss Gamma 0.2; div(((rho*nuEff)*dev2(T(grad(U))))) Gauss linear; //turbulence model div(rhoPhi,k) bounded Gauss Gamma 0.2; div(rhoPhi,epsilon) bounded Gauss Gamma 0.2; //other turbulence model div(rhoPhi,R) bounded Gauss Gamma 0.2; div(rhoPhi,omega) bounded Gauss Gamma 0.2; div((rho*R)) Gauss linear; div(R) Gauss linear; div(U) Gauss linear; div((muEff*dev(T(grad(U))))) Gauss linear; div((muEff*dev2(T(grad(U))))) Gauss linear;
边界条件:
入口速度入口压力零梯度
出口为压力无反射边界条件
