DPM concentration in a cell using Fluent UDF

(1/1)

Hi,

I am working on modelling of heat transfer from the discrete phase (lagrangian) to the continuous phase. I need to find out the concentration of the discrete phase in the cells. Based on the concentration, I can modify the equation used for heat transfer between the two phases. Because when the particles are moving very close to each other, the effective heat transfer coefficient will be very different from the heat transfer coefficient of a single particle.

Could any one here also tell me about the literature in dealing with heat transfer from spherical particles that are closely spaced?

Thank you.

You can use

C_DPMS_CONCENTRATION(c,t)

to get the concentration of discrete phase in the cell.
