Dear All,
I’m currently dealing with heat transfer analysis on MFIX. I’m trying to simulate my conical spouted bed system in DEM but I have a few questions about it.
-
When I wanted to give thermal conductivity to the solid particle, I had to select Musser’s equations. I have just found Musser’s PhD thesis and he summarized the heat transfer equations on MFIX. Are all of the heat transfer equations in Musser’s thesis implemented on MFIX?
-
To calculate the Nusselt number, some correlations exist in the literature. As you know, Marshal’s correlation is suitable for DEM, but I saw lots of Gunn’s correlation in the literature. In MFIX-DEM, which correlations are used?
-
Is there any document that explains heat transfer equations fully in MFIX? In the 2012 DEM Equation sheet, some equations are missing I think.
-
Finally, I want to give heat flux at a specified height. This specific height is in the fountain region of the spouted bed and close to the static bed height of the spouted bed. When I created a region and assigned it as a wall boundary condition hydrodynamics of the spouted bed failed. Particles hit the region that I defined and bounce back to the bed. How can I define it ? In more detail, we are trying to simulate the CSP system, and the point that I want to give heat flux is the focal point of sunlight.
