XiFoam equations
Hi
Could someone please translate the XiFoam code below into equation form? I want to check how they relate to the equations from Weller's paper: Basically I want to see how Us(.)(grad (rho Xi)) in the transport equation for Xi equals fvm::div(phi + phiXi, Xi, "div(phiXi,Xi)") - fvm::Sp(fvc::div(phiXi), Xi) surfaceScalarField phiXi = phiSt – fvc::interpolate(fvc::laplacian(turbulence->alphaEff(), b)/mgb)*nf + fvc::interpolate(rho)*fvc::interpolate(Su*(1.0/Xi - Xi))*nf; fvScalarMatrix XiEqn ( fvm::ddt(rho, Xi) + fvm::div(phi + phiXi, Xi, "div(phiXi,Xi)") - fvm::Sp(fvc::div(phiXi), Xi) == rho*R - fvm::Sp(rho*(R - G), Xi) - fvm::Sp(rho*max(sigmat-sigmas,dimensionedScalar("0",sigmat.dimensions(), 0)),Xi) ); XiEqn.relax(); XiEqn.solve(); -------------------- Thanks so much! ak |
