Vicktor is on a distinguished road
Dear Friends,

i'm new here, so would be very thankful if you professonials would help me.

In my Ansys cfx Simulation i injected 10 micro meter water droplets (Euler-Lagrange methode) in a planar blade passage. I wanted to know if it is possible to define the droplet-density of the water droplets (material -> water) as a dynamic Expression of the current force from the surrounding Phase working on the water-droplets. If it is possible, how can i do this in Ansys cfx?


Kind regards,
Vicktor

What do you mean by the "current force from the surrounding phase"? Do you mean the continuous phase pressure? Or the drag force on the droplet?

I would just give it a try and see if it works. It will tell you if you cannot do it. The list of available variables are in the CFX documentation reference manual.
