 July 29, 2008, 07:55 Urgennt : DPM Mass Flow Rate #1 chouki Guest   Posts: n/a Sponsored Links Hello, I'm solving 3D unsteady flow using DPM. Particles are injected at the inlet and I want to get the mass flow rate of dispersed phase at the outlet. Could you help me please? Kind regards. Chouki

 July 30, 2008, 10:24 Re: Urgennt : DPM Mass Flow Rate #5 chouki Guest   Posts: n/a Thank you very much again Hossam, I followed the steps you gave me in the previous message I found the following data at time = 4.0 s: Fate: escaped- zone 20 (outlet), Number (600000), Mass (kg) : initial = 190, final =190, change =0. I consider that the total mass of dispersed phase left the domain across the outlet is 190 kg during 4.0 seconds. Is is true? Could you like please explain me what it does mean by initial mass and final mass. Kind regrads, chouki
