Induced Virtual Mass force

sarrazs · September 26, 2017, 15:18

Hello,

I'm doing two-phase flow simulation for a bubble column. I want to implement a new correlation for the virtual mass force. In this new correlation, we have the induced virtual mass force due to other bubbles presence. So for a single bubble, for every time step, I need to take into account all the surrounding bubbles accelerations and distances.
For example, for a bubble n, I set a radius rs, and every bubble inside the rs radius will be taken into account.
Is it possible to do this with CFX user routine?

Sounds possible in a user fortran routine for a langrangian particle tracking model.
