hello guys,
I am hari . I am working on compressible interfoam . I couldn't understand the pressure equation used in pimple algorithm in PEqn.H in compressible inter foam. can anyone help me explaining it. i am attaching the equation below.
p_rghEqnComp1 =pos(alpha1) *( ( fvc::ddt(alpha1, rho1) + fvc::div(alphaPhi1*rho1f) - (fvOptions(alpha1, mixture.thermo1().rho())&rho1) )/rho1 - fvc::ddt(alpha1) - fvc::div(alphaPhi1) + (alpha1/rho1) *correction ( psi1*fvm::ddt(p_rgh) + fvm::div(phid1, p_rgh) - fvm::Sp(fvc::div(phid1), p_rgh) ) );thanks and regards
