Gravity-assisted melting in a horizontal cylinder heated by external forced convection

Melting and convection of phase change materials in different shape containers: A review

“…Analytical results showed a good agreement with experimental data for wide range of the Rayleigh numbers. Also, the influence of buoyancy-driven convection was insignificant when Ra <105 .An experimental study of unfixed melting inside a horizontal tube subjected to an external forced convective heating condition is presented by Maldonado et al[58]. The experiments were conducted for a wide range of the Stefan (0.026-0.053) and Archimedes numbers (8.76x106 -…”

“…The results revealed that the Stefan number, Ste, phase change temperature range and the capsule radius were the main parameters that govern the melting process. Also, the agreement between analytical and experimental results was significantly improved when the results were obtained considering phase change temperature range and the natural convection in the liquid phase instead of considering the process to be dominated by conduction only.A summary of the studies focusing on melting of phase change materials contained within cylindrical vessels[46][47][48][49][50][51][52][53][54][55][56][57][58][59][60][61][62][63][64][65] are provided inTable 4. Specifically, cylindrical vessels' orientations, the imposed boundary conditions, PCM type, adopted methodologies/techniques, along with thehighlights of the findings are summarized.…”
