a question about bubbleFoam
 

Hi FOAMusers,

I want to use the bubbleFoam solver to simulate a liquid jet in a air cross flow. The liquid jet is water, which is injetted by a nozzle with a diameter of 0.5mm.

When I user bubbleFoam to simulate this case, I am not sure which values I should set for da and db (diameters of phase A and phase B). From literater I know that these two diameters are used to calculate the drag force.

Could anyone tell me, how can I choose the values for da and db?

thanks in advance!!!

trying to use solver twoPhaseEulerFoam instead. There you can choose "dragPhase a;" and thus the drag force is only in function of da and you dont need to worry about db.
