Mathematical simulation of particle deeposition on a channel wall

The problem of particle deposition connected with dust deposits in steam generators of NPPs with gas cooled reactors, radioisotope transport and deposition in reactor plant cooling circuits is discussed. The approximate analytical solution for the Fokker-Planck kinetic equation in near-the-wall section is constructed, and the algorithm for this equation numerical solution based on utilization of the methods used for electric network calculations is suggested as well
