DPM in fluent
 

I am trying to run DPm with kE model in fluent 6.0. For a size of coal with diameter day 2 mm, with the inlet and the outlet bioundary conditions specified, whatever may be the number of time steps I give the particle trajectories are incomplete. The particle particle interactions and the effect of turbulent fluctuations of the fluid on the particle were not considered. the number of grids is as high as 10 lakhs.Why is it so.?

Hi

1) your particle diameter is huge in comparison with the diameter that I have seen in other simmulations (usually less than 1.0E-04m), as result your particles have a high momentum.

2) increase the maximum number of time steps or increase the length scale.

have you teack the particle path??

I have tried both. It still doesn't work out. What to do?
