Effect of eddy formation on gas mixture homogeneity near a substrate in a vertical reactor for CdHgTe deposition

Abstract

This paper presents simulation results obtained for an unsteady-state flow of a multicomponent gas mixture in a flow-type vertical reactor using a three-dimensional mathematical model that takes into account the convective mass and heat transport, compressibility, viscosity, and thermal conductivity of the components and gas flow turbulization. We identify the gas dynamic mechanism behind eddy formation in the reactor and examine the influence of the viscosity, density, and speed of the flow components on eddy formation and the homogeneity of the gas mixture over the substrate.
