Abstract
This paper attempts to review some of the different physical contexts in which partially molten (or partially frozen) zones occur, and to outline some of the problems which one encounters in attempting to model such zones realistically. The nature of averaged equations for reactive two-phase regions is first discussed for the case of a solidifying alloy, in which the fluid velocity is zero. Four principal examples are then discussed, in which fluid flow is important. These are alloy solidification, magma transport, frost heave, and the solidification of igneous intrusions. Various similar mathematical features in the models are pointed out, as well as some common difficulties in their formulation.
