TWO-DIMENSIONAL CONVECTIVE DIFFUSION OF A RADIOACTIVE IMPURITY WITH ALLOWANCE FOR SORPTION IN A POROUS MEDIUM
M. L. Zhemzhurov and G. Z. Serebryanyi UDC 621.311.25:519.6:532.546 A mathematical model of the two-dimensional convective diffusion of radionuclide transfer in a porous medium has been considered. A fundamental solution in the form of Green's function has been obtained for this model. The analytical expressions of the impurity-concentration distribution for stationary conditions and for a few kinds of boundary conditions have been given.
