How to include multiple lagrangian particle clouds?

lf.lopez18 · August 5, 2020, 22:28

Hi!

I am using reactingParcelFoam to study spray flames. Now I want to add some "virtual particles", whose velocity I want to calculate from a formula, not from a balance of forces as conventionally. So I made a custom library from kinematic libraries (basicKinematicCloud, KinematicCloud, KinematicParcel, etc...). You can call it virtual library, so I changed the files names to: basicVirtualCloud, VirtualCloud, VirtualParcel, etc... and all the content inside them from "kinematic" to "virtual".

I have some questions:

How to add this particle cloud to the custom library?
How to impose the particle velocity instead of calculating from balance of forces?

Thanks in advance.
Felipe.

1.) There are several nice tutorials out there regarding this topic. Quick googling for example gave me this: https://www.foamacademy.com/wp-conte...ons_slides.pdf

2.) In principle you can use the reactingParcelCloud and simply change the method of calculating U in ReactingParcel.C to something that suits your needs. In my OF-Version it is at line 550.
