MPPICFoam/denseParticleFoam 对于重力的考虑
-
@李东岳 李老师,最近在做实验,昨天又试验了一下,p场稳定了一些但是还在波动,但是U.air场变得混乱了,李老师有空可帮我看下吗,还有一个问题719e060c-5757-402d-b40a-0d978c2be0a7-tp_of10.zip
DPMFoam中的UcEqn.H:
fvVectorMatrix UcEqn
(
fvm::ddt(alphac, Uc) + fvm::div(alphaPhic, Uc)- fvm::Sp(fvc::ddt(alphac) + fvc::div(alphaPhic), Uc)
- continuousPhaseTurbulence->divDevRhoReff(Uc)
==
(1.0/rhoc)*cloudSU
);
UcEqn.relax();
volScalarField rAUc(1.0/UcEqn.A());
surfaceScalarField rAUcf("Dp", fvc::interpolate(rAUc));surfaceScalarField phicForces
(
fvc::flux(rAUccloudVolSUSu/rhoc) + rAUcf(g & mesh.Sf())
);if (pimple.momentumPredictor())
{
solve
(
UcEqn
==
fvc::reconstruct
(
phicForces/rAUcf - fvc::snGrad(p)*mesh.magSf()
)
);
}///////还有就是这一项代表了什么意思呢////////
surfaceScalarField phicForces
(
fvc::flux(rAUccloudVolSUSu/rhoc) + rAUcf(g & mesh.Sf())
);
