Abstract The melting of the phase change material (PCM) octadecane, confined in a rectangular cavity heated from bottom, is numerically studied. Simulations are performed through finite element software order to analyze impact metal fins within enclosure on time. results analyzed terms time-dependent position front, average liquid fraction, and time needed for PCM melting. obtained outcomes highlight how, with low number metallic fins, initial regime dominated by conduction at certain gives way convective characterized Rayleigh–Bénard cells, full agreement theoretical analysis. On contrary, high only mechanism that governs heat transfer rapid slows down when front reaches top fins. More specifically, addition yields reduction complete up 90% cases. reported provide new insights regarding mechanisms involved PCMs bottom-heated enclosures.
