Abstract

The flow structure and impurity distribution in an axisymmetric cylindrical space is obtained from the system of equations of convective heat and mass transfer in the Boussinesq approximation for different variants of the gas inflow and outflow conditions. The variation of the average impurity concentration in the space investigated, obtained as a result of numerical calculations, is compared with two limiting cases of expulsion of the contaminated gas: the “gas piston” case and total mixing. The dependence of the velocity and impurity concentration fields on the regime parameters (Reynolds, Grashof, and Schmidt numbers, velocity profiles at the gas inlet and outlet) and the geometric and design parameters (elongation of cylinder, inflow and outflow geometry) is investigated numerically.
