MRF and DPM methods
 
Hi, All friends,

I am calculating drops distribution in a baffle tank with rotating impeller (Fig. 16.2.3, pp.16-7, Fluent manual) by using the multiple reference frame in conjunction with the discrete phase model. I find the drops DPM concentration near wall is extremely high (order of 10^6 kg/m^3). Please tell me why this happens and how to get a reasonable result. Thanks you very much for your help.

I am looking forward to your reply.

With best regards,

You

DPM problem
 
Dear everyone:

I am using DPM method to simulate drops distribution in a compartment. The residuals are always oscillatory and don't converge. Could you please tell me how to make my solution convergence ? Thank you very much for your help.

With best regards,

You
