Abstract

In this study, one-dimensional Stefan problem with air-gap resistance in the rectangular mold is considered and the thermal characteristics are examined by using the enthalpy-based simple implicit finite-difference scheme. The enthalpy and temperature are nondimensionalized to obtain general solutions. The temperature distribution and the locations of solidus and liquidus line are obtained and the effects of major parameters on the thermal characteristics are investigated.
