Thermophoretic effect

I have ran a series of isothermal simulations. Particles are injected in a 2-D flow over a flat plate, and the particles that hit the plate have been counted.
Now, I want to run the experiments with a temperature gradient, to study thermophoresis. The problem is that so far, the results are exactly the same as for the isothermal conditions. I would appreciate some input on what may cause this? My settings: Models: Multiphase: off Energy: on Viscous - standard k-e, Enhanced Wall Fn Radiation - off Species - species transport discrete phase - on solidification & melting - off acoustics - off Under the discrete phase->edit: physical models: thermophoretic force + pressure gradient force. In injections, T=673.15K The temperature of the surface of interest is 573.15K, all other walls are 673.15K At the solution initialization, the temperature is also set to 673.15K. |
