DPM Particle Heating UDF
Recently I've been working on a discrete phase modelling for small particles inside a fluid. The reason why I am using DPM is because of low volume fraction and ability to track particles with discrete phase modelling.
I succesfully formed my model. However to further improve, I have to include additional inputs.
I have to apply heat source to the particles depending on their location. I know that there is no possible option to implement particle heat source so I am using DPM_LAW to include that additional heating as a temperature change to the particle. However, with the temperature change, fluid near the particle has to be updated, but I see no change in the fluid velocity or temperature. So DPM_LAW only changing particle temperature. I tried using DPM_Source to add energy source to the cell that particle is in.
I am able to add some kind of source to the cell but I am not sure it is the true way to do that. So I am probably missing a point and misunderstood something on the UDF manual.
But why not when I change the particle temperature through DPM_LAW, it is not directly added to the energy equation for heat transfer calculations. And is there a better way to do what I am trying to do? I mean adding a energy source to the cell is too much. By the way I enabled coupled solution, so interactions between fluid and particles are included.
Thank you in advance for any kind of information you can provide regarding this issue.
