Brownian force model in DPM
 

Hi everyone,

I am modeling nano-liquid droplet motion in fixed gas velocity field. When I include brownian force in the equation of particle motion, I got odd results.

I set the temperature of droplet and gas to same temperature. And I start the calculation. But droplet temperature went to 1 K as soon as droplets were injected. What is happening?? Acutually, this doesn't happen when I calculated first time. But this happened when I started another calculation. I am really confusing. So could anybody help me??

Thanks, AKR

I think by now you know the default brownian force model does not work and you will have to write a udf to account this force
