...) incorporate both fluid motion outside of the pellet and heat transfer in the pellet and (2) capture the complex physics of the problem, including the formation of a shell outside the pellet once dropped in the bath. In practice, these requirements make adaptive mesh refinement (AMR) a viable approach...

... for CCC, one has to consider both the mass and the heat transfer aspects to arrive at an optimal design. There are a few studies reported on the desublimation-based CCC, and they have focused on the development of an efficient cooling system to enhance the rate of desublimation. In this context, we...
