Hi everyone. I am doing bubble DPM and need to inject a given amount of bubbles, now how do I set the bubble volume fraction I want to inject, or how do I know how many bubble particles is the right number.

First, what are the details of your injection? type, bubble diameter (fixed or PSD) , etc ..

You can control the injection by mass flow rate, start time and stop time. Note that in DPM mass flow rate is a DISCRETE mass flow rate, i.e. mdot = number of particles per sec * particle mass
