SUMMARY:Some dynamics of brine and compressible vapour flows in permeable 
 conduits - Prof. Herbert Huppert\, FRS\, Department of Applied Mathematics
  and Theoretical Physics\, Cambridge

DESCRIPTION:The talk will discuss two situations.  First\, the flow of a v
 iscous compressible gas through an axisymmetric or two-dimensional porous 
 conduit.   Applications include the release of magmatic volatiles from a m
 agma chamber beneath an active volcano and the discharge of geothermal flu
 ids. The results are also relevant to evaluating the consequences of an ac
 cidental release of carbon dioxide from a storage reservoir within the Ear
 th\, as might happen at a carbon capture and storage (CCS) site. The secon
 d part will describe the input of hot brine into a layered porous medium t
 o 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.\n
