Hi, everybody.
I'm doing: particles transport is modeled by a convection-diffusion equation in ansys fluent 2023R2.
- steady-state model.

- multiphase model: Eulerian.

-Primary phase material: Newtonian.

-second phase material: non-Newtonian.
- laminar model.
I model the transport of the particles using a convection-diffusion equation due to the motion of the mixture, composed of the primary phase and the second phase.
Assume that the particles are influenced by the motion of both the primary phase and the secondary phase.
A mixture of domains contains particles (C_UDSI(c,t,0) ) which I want to control diffusion flux depending on both the primary phase and the secondary phase.

I am very confused when implementing the convection-diffusion equation using UDF.

I don't know what the most accurate way to describe the equation is.

I am looking forward help from experts and knowledgeable users
Thanks you so much!!!
