Tiny size particle question. (DPM)
 

I used fluent for simulating the movement of the tiny size particles. I use the k-e turbulence model. DPM model for particle. droplet Injecte from surface and the number of particles is 1600, the size of particles is 1e-6m. The wall can trap the particles. According the theory, the efficiency should be lower than 50% to 10%, However the fluent gave me the 90% efficiency. Who can help me to find the reason?

what is the reynolds number and the turbulence boundary conditions?

Perhaps you haven't enough particules.
