Abstract
The present work investigates the segregation of particles due to the motion of front of solidification in
phase change materials (PCMs) and its dependence with shape and dimension factors adjustable by
design. It is shown that for particle diameters <10 mm this kind of segregation is the dominant mechanism
overcoming the gravitational settling. Utilizing a simplified geometrical model on from the solution
of Stephan problem, an analytical expression for the dependence of segregation on such factors
was derived. The results show that shape and dimension factors profoundly affect the segregation which
implies that the particle segregation can be controlled in great extent through system modeling and
design optimization.
