Summary

The authors show an efficient algorithm to solve the transient behaviour of direct contact melting, considering the solid movement by external forces exerted on a solid body as well as that by melting. The method is based on the enthalpy method, but is especially devised to satisfy the force balance on solid phase with velocity variation. It is examined through two test problems. The first one is that the system gradually approaches the steady state after the start of melting. The second one deals with a rather complicated situation of a copper block above a melting temperature being cooled by ice. It was verified that the present methodology can deal with such a conjugate problem feasibly and simply.
