The sum-up of forces on particles
Hi, guys, I am using the solver 'icoUncoupledKinematicParcelFoam' to do some validations.
My question is, to a particle, or a parcel, the force on it should be from both environmental field (like drag force) and collision. Now, I can find the programme for drag force, gravity force, etc, I can also find the programme for collision spring force as well. But, still can't find where they are added together for the particle or parcel. Really confused... |
Try looking at
Code:
$FOAM_SRC/lagrangian/intermediate/lnInclude/kinematicParcel.C Code:
const forceType& forces = td.cloud().forces(); Good luck. |
Thank you very much!
I found that and read it. By my understanding now, the velocity of parcel should be calculated twice, the one is in 'KinematicParcel.C' for particle forces, like drag force and gravity, while the other one is in 'CollidingParcel.C' for those forces due to collision. So, actually, the forces on the parcel are not collected altogether, but divided into two parts. Am I right? Thank you very much again! |
Hello.. did you ever find an answer to this?
