Abstract

In the present study melting experiments, performed with different geometric test configurations, are reported. The investigation encompasses the melting process adjacent to a heated vertical surface and inside a vertical as well as horizontal heated cylinder. All studied processes show common features and can be described by two-regime models. In the first stage of the process the conduction regime is valid, directly followed by a quasi-steady convection regime which can be described by a correlation of the form Nu = f(Ste, Ra). An appropriate transition criterion allows for the transition point between both regimes.
