Hi,

Now I want to simulate combustion of particle in reacting multiple species flow.There are six laws about particle's heat/mass transfer calculations in fluent.How can I change these laws to suit my problem using a user-defined fuction?

If you have some cases about it,Would you like to give me?

Thank you.

Sincerely, Devy

Hi,

I also use dpm for a solid combustion problem. I use inert particles with DEFINE_DPM_SOURCE(dpm_source, c, t, S, strength, p).

There I modify, diameter and use S->Mass to simulate mass transfer.

Hope it helps.

Thank you for your help. But in my problem,both the reactant(Al) and the product of combustion(Al2O3) are particles.This means I must track Al and Al2O3 particle trajectories.Now I just know how to track the reactant(Al) particle trajectories,and I don't know how to track the product(Al2O3) particle trajectories.

Would you like to give me some advice?Thank you.

regards Devy
