Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "An adaptive-grid finite-difference method is applied to a model for non-isothermal, coupled flow and transport of brine in porous media. In the vicinity of rock salt formations the salt concentration in the fluid becomes large, giving rise to disparate scales in the salt concentration profiles. A typical situation one encounters is that of a sharp fresh-salt water interface that moves in time. In such situations adaptive-grid methods are more effective than standard fixed- grid methods, since they refine the space grid locally and hence provide for substantial reduction in number of grid points, memory use and CPU time
