Abstract

Melting phenomena around horizontal tubes with and without axial fins were investigated experimentally. While melting around a horizontal tube results in the well known deformation of the solid-liquid interface, a different heat transfer behavior is to be found by mounting nearly isothermal axial copper fins or nearly adiabatic axial PVC fins. Moreover melting patterns and heat transfer rates are influenced by the geometric fin arrangement. Mean heat transfer rates are correlated, depending on the different investigated convection schemes. Special attention was drawn to the fluid flow behavior at the interface, where Görtler vortices could be detected.
