Heat and Mass Transfer in Cesium Evaporation from Graphite Surface in Argon

Abstract

The aim of the present work is mathematical modeling of the heat and mass transfer of ¹³⁷Cs under the action of low-temperature equilibrium plasma flow on sections of graphite contaminated by radionuclides. The methods of investigation are calculation of the temperature and mass rate of evaporation of radiocesium by solving a system of quasi-homogeneous nonstationary heat conduction equations with boundary conditions of the first and third kind, which take account of mass transfer, by means of finite-difference elements using the ANSYS package.
