Close-contact melting (CCM) has long been studied as a special melting process featuring very high heat transfer rates as a result of the low thermal resistance across the thin melt film between the PCM and the heating surface. From: Renewable and Sustainable Energy Reviews, 2022 ...
A mathematical model describing the close-contact melting process of phase change material in a spherical enclosure is developed. The governing integro-differential equations are solved by the numerical integral technique. By considering the two-phase interface shape more precisely, the variation of the...

The latter phenomenon is called close-contact melting (CCM), because only a thin molten layer separates between the solid and the hot surface, as the melt is squeezed to the sides by the descending solid bulk. The present work demonstrates a numerical model that combines the enthalpy method ...

Close-contact melting heat transfer characteristics, including natural convection in the liquid region in a horizontal cylindrical and elliptic capsules with arbitrary aspect ratio, were studied theoretically. Special attention was focused on the flow pattern of natural convection in the liquid phase when...
