MATHEMATICAL SIMULATION OF THE MIGRATION OF RADIONUCLIDES IN A SOIL MEDIUM UNDER NONISOTHERMAL CONDITIONS WITH ACCOUNT FOR CATALYTIC MICROPARTICLES AND NONLINEAR PROCESSES

The problem of mathematical simulation of the vertical migration of radionuclides in a catalytic porous medium under nonisothermal conditions is considered. A numerical solution of the corresponding one-dimensional nonlinear boundary-value problem is obtained by the fi nite difference method. Numerical experiments are carried out and their analysis is made.
