LINEARIZED DIFFUSION IN A RELAXING CONVECTING GAS WITH PRANDTL AND LEWIS NUMBER EFFECTS

Abstract

The linearized model of an ideal gas with diffusion processes and rate reaction is applied to one-dimensional unsteady motion geneated by initial non-uniformities of state and velocity. The time-dependent system resembles that of steady, two-dimensional, free mixing of jet or wake type. The temporal and spatial chracter of the profiles of flow variables is stdied analytically for the conditions of state and velocity non-uniforities with various combinations of Lewis and Prandtl numbers. This model correspons to a two-dimensional viscous free mixing flow of an ideal dissociating gas with state variations of temperature and concentration. (Author)
