The talk will discuss two situations. First, the flow of a viscous compressible gas through an axisymmetric or two-dimensional porous conduit. Applications include the release of magmatic volatiles from a magma chamber beneath an active volcano and the discharge of geothermal fluids. The results are also relevant to evaluating the consequences of an accidental release of carbon dioxide from a storage reservoir within the Earth, as might happen at a carbon capture and storage (CCS) site. The second part will describe the input of hot brine into a layered porous medium to mimic porphyry copper deposition. The input will be seen to transition from a hemispherical shape to a long, thin gravity current, both in the theory and on the bench in a simple experiment.
