| Abstract: | The equations of two-phase-flow arise from statements of conservation of mass, momentum, and energy. In addition to the conservation laws, a series of phenomenological laws must be prescribed to describe the interaction between the two phases. It is the choice of these phenomenological laws that makes two-phase-flow theory challenging.
In this presentation I will outline the choices of phenomenological laws that have been used thus far in magma dynamics, and their physical consequences. I will give an overview of the basic physics of compaction, and the important role of the compaction length, the natural length-scale in compaction problems. I will highlight which areas of the theory seem robust, and which are in need of further development. |
