Hello Foamers,

I need help from expert in multiphase flow.

I want simulate a three phases flow including Air, water and particles. As classic issue, I would like to use Eulerian method. Therefor, I would like to pick up multiphaseEulerFoam. However, because the particle is only existing in the water, I dont know what is corrected settings to avoid the mix between air and particles without water.

For example, in phaseProperties.

type basicMultiphaseSystem;

phases (particles air);

referencePhase air;

particles
{
type purePhaseModel;

diameterModel constant;
constantCoeffs
{
d 3e-4;
}

alphaMax 0.62;
residualAlpha 1e-6;
}

air
{
type purePhaseModel;

diameterModel none;

residualAlpha 0;
}

blending
{
default
{
type continuous;
phase air;
}
}

surfaceTension
{}

interfaceCompression
{}

drag
{
particles_dispersedIn_air
{
type GidaspowErgunWenYu;
residualRe 1e-3;
}
}

virtualMass
{}

heatTransfer
{
particles_dispersedIn_air
{
type RanzMarshall;
residualAlpha 1e-4;
}
}

phaseTransfer
{}

lift
{}

wallLubrication
{}

turbulentDispersion
{}

Could anyone advise me how to setup this settings for three phases flow?

Thanks very much!
