Injection of water droplets using DPM

Mona · April 1, 2012, 02:59

Hi,

I want to simulate the injection of water droplets in the flow of hot air using discrete phase model. The idea is to use a curtain of water sprays to avoid the spread of heat from one part of the compartment to the other part (in case of fire).

I dont have any previous knowledge about DPM. So, for the start I have done the 2D simulation just to get the idea of how to do DPM. But when I want to define the "injection", the only option I have is the "inert" particle type. I guess it means that I wont have any vaporization of water droplets (law1) which is not correct.

I would be thankful if anyone can help me regarding this problem.

Thanks in advance.
Mona

do you have the energy equation on?

Hi,

Yes, I do.

well,It is really easy bro
just turn on 'species' in the model menu and then choose one of its options like 'species transport'.....then it's up to u to choose proper mixture and material properties..
