I have a simulation which has dispersed phase "air1" and "particle" with phaseProperties like below.
Code:
air1 { type pureIsothermalPhaseModel; diameterModel velocityGroup; velocityGroupCoeffs { populationBalance air3; shapeModel spherical; sizeGroups ( f1 {dSph 4e-3; value0.4;} f2 {dSph 5e-3; value0.2;} f3 {dSph 6e-3; value0.4;} ); } residualAlpha 1e-8; } particle { type pureIsothermalPhaseModel; diameterModel velocityGroup; velocityGroupCoeffs { populationBalance air4; shapeModel spherical; sizeGroups ( f4 {dSph 7e-3; value0.2;} f5 {dSph 8e-3; value0.6;} f6 {dSph 9e-3; value0.2;} ); } residualAlpha 1e-8; } Code:
particle { type pureIsothermalPhaseModel; diameterModel velocityGroup; velocityGroupCoeffs { populationBalance air4; shapeModel spherical; sizeGroups ( f4 {dSph 7e-5; value0.2;} f5 {dSph 8e-5; value0.6;} f6 {dSph 9e-5; value0.2;} ); } residualAlpha 1e-11; } What should I replace/change to make the simulation run well? I've seen the titania synthesis in tutorial have smaller phase size and can be executed with no problem. What should I consider in setting the phaseProperties? thanks in advance |
