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
