Sliding contact melting. The effect of heat transfer in the solid parts

In an earlier paper. the phenomenon of steady melting and lubrication by sliding contact was studied based on a model in which: (a) the block of phase-change material was isothermal and at its melting point, and (b) the solid slider (heater) was either isothermal or adiabatic. These simplifying assumptions had the purpose of decoupling the liquid-film phenomenon (melting and lubrication) from the heat transfer processes that can occur in the two solid bodies. The objective of the present note is to relax the assumptions (a) and (b), and to document the effect of peripheral heat transfer on the sliding-contact melting phenomenon. The chief conclusion of this note is that the lateral conduction heat transfer can have a significant effect on the melting velocity.
