Hi,

I simulate a combustion in an axisymmetric domain. I use the dpm-model (solid combustion) with a mass and an energy source.

For the axisym probem, do I have to use the full particles loading or 1/(2pi), or in other words, does Fluent work with a sort of 1 rad piece of cake (or pi/4, ???) for axisym cases?

I don't find any mention of it in UG.

Thanks in advance.

Hi. If you are using axisymmetric modeling option. You just give full load based on inner and outer radius fluent will calculate required loading, Regards, Rahul

Hi,

I don't agree with you. If I have let's say 1000 particles in my case, I will certainly put less in axisym.

Fluent will probably extrapolate the load.

The question is with which factor?

If the particle load is calculated in the same way as the inlet properties, then Rahul is correct.

How to define inlet properties for axisymm. is described in the Fluent manual.

I agree, but I don't have any inlet. I put n particles in the system (dpm - injection via file) at t=0.

My point being that if the definitions are the same, Rahul are correct. Whether your case have an inlet or not is irrelevant. The method is the same.

So I think that if your case in real world have 1000 particles, your axisymm case should have 1000 particles (like inlet definition).

OK, I'll try to go futher to investigate it.

Thanks for your contributions.
