Hello Everybody,
I am currently dealing with a simulation of particles in closed geometries (Cylindrical Pipes). Till now, I used the DEM solver in Star-CCM to simulate the flow of particles in vertical pipes. The flow is in dense phase (packing fraction ~ 60%) and is solely driven by gravity. Hence I decoupled the air and the particles and got good/accurate results.
Now, I need to extend this study for heat transfer applications in which, the particles are heated from the pipe wall. Hence I need to simulate a 2-way coupled DEM problem enabled with heat transfer between particle-particle, particle-wall, particle-interstitialAir and interstetialAir-wall. The particle size is big enough to occupy a decent volume of every mesh cell. So, I would like to know if CFDEM would be able to solve this problem or not before I dive into the actual implementation.
( I attempted this problem in Star-CCM earlier but it didn't work. In Star-CCM, every particle is considered as a single point, no matter how big of a volume it occupies in a mesh cell. The heat transfer between the interstitial air and particle is thus considered using a convective heat transfer coefficient. But this won't work in my case. Hence I wanted to move into CFDEM Coupling to solve this problem as a volume fraction term is included in the CFD equations.)
So can anyone help me in knowing if CFDEM works for my problem
