Question about DPM velocity and Total flow rate
I'm a beginner for DPM function in ansys fluent. I want to ask a few question about DPM settings:
- In the "point properties" what is the meaning of velocity and total flow rate. It's that the "velocity" is use to define the Initial velocity of the particles? And what is the meaning for the total flow rate (especially for a single point)?
- Is the velocity and total flow rate don't connect with the set up on the inlet boundary condition(if iI use mass flow rate as a inlet boundary condition)?
- How should I define the inject of particle without any initial velocity. Set 0 m/s and 0 kg/s for velocity and mass flow rate can't get any result for particles tracking. Should I set up both value as a vey small number, for example "1e-15"
Hope you could answer my question, Thank you.
