whats the mathematical equivalence of this formula?
which equation is used in rhoCentralFoam? Code:
// --- Solve momentum solve(fvm::ddt(rhoU) + fvc::div(phiUp)); U.dimensionedInternalField() = rhoU.dimensionedInternalField() /rho.dimensionedInternalField(); U.correctBoundaryConditions(); rhoU.boundaryField() = rho.boundaryField()*U.boundaryField(); volScalarField rhoBydt(rho/runTime.deltaT()); if (!inviscid) { solve ( fvm::ddt(rho, U) - fvc::ddt(rho, U) - fvm::laplacian(muEff, U) - fvc::div(tauMC) ); rhoU = rho*U; }
