| Abstract | In this paper we describe the physical controls upon the rate of vaporisation of liquid as it is injected into a hot porous layer. We show that if liquid is injected at a relatively high rate of injection, then a low fraction of the liquid vaporises and the porous layer becomes filled with hot liquid. However, at low rates of injection, a high fraction of the liquid may vaporise. We also describe a new and fundamental instability that can develop at a migrating liquid-vapour interface if the rate of injection is sufficiently small. |
