How to set correct mass flow rate for lagrangian particles ?
 
Dear All

I am using OF 1.6.x
I am running a simulation where a simple nozzle is injecting compressible gas + solid particles jet into an open atmosphere.

I know the mass flow rate of the particles, density of the particles and the particle diameter distribution from the experiments.

I am using the patchInjection option to inject particles from the inlet patch. The code works without a problem

But I am not quite sure how to set the mass flow rate of the particles correctly in the kinematicCloud1Properties file

My simple question is this:

Can anyone please tell me what is the relationship between
parcelsPerSecond, massTotal, volumeflowRate, SOI and duration ?

Please help me

Thanks
Vaidya
