how to control the number of particles ejected using DPM?
I'm trying to eject droplet particles using DPM technique, however, I couldn't find the way to determine the number of particles to be ejected?
Can anyone help me regarding this matter? and If I can't determine the number of particles what else I can control ? |
In the Discrete Phase Model window, you go to "injections", and you create a new one.
In the Set Injection properties window, you have the following box : "Number or particle streams", which is fixing the number of p. to inject for your simulation. Be careful to the difference between steady and unsteady tracking ! Best, Mat |
@ Mat_ : do You know how the injected mass flow rate is determined during the injection , as it is a bit confusing for the case of the unsteady tracking , we do have Particle time step size , number of steps , and the start stop injection time

dear Yahya, do you know how to enable the "droplet" in "set injection properties" tab, since the "droplet" is not available in my case. thanks a lot.
|
Well if you want you can communicate with me through facebook or skype?
Because i dont understand ur question clearly Its ok for you? |
Dear Yahya, thank you so much for concerning my problem. however I think I just need to ask you whether I have to turn on "species transport model" to be enable to turn on "droplet" option in "set injection properties" tab. since I did it and it worked. thanks in advance.

I think if u just enabled the DPM model it will directly enabled the droplet
The things that you need to do is to define primary phase then the seconadry phases (droplets) then after defining the droplets materials in the set injections you should see the droplet with the type of material you wish to use (any of the secondary phases) tell me your progress and im ready to help you regarding the DPM, since im done with this issue |
Well i dont think you need to use this species model to enable them, i dont remember that i used it
