Mass flow rate of the DPM mass sourse ??

May 21, 2005, 11:43

recently ,i am working on the atomization of liquid . with fluent 6.1 ,I also selected a single point injection in a axisymmetrical case, steady calculation, under spray model ,choose the droplet breakup and collision. The problem is that the the mass flow rate in the monitor for convergency check is always equal to zero!

monitor set as follow: Solve- Monitors -Volume. (a)Increase the number of monitors to 1. (b) Turn on Plot and Print and click Define.... (c) Under Field Variable, select Discrete Phase Model... and DPM Mass Source. (d) Under Cell Zones, select fluid i am very confused about it ,waiting for your answers 3X!!!

let me know your outlet boundary condition. change outlet boundary condition then try again

When you make a figure with particle tracking. fluent-> Graphics and animations -> particle tracks
What do you see?
