LINEARIZED DIFFUSION IN A RELAXING GAS
Abstract
The linearized model of a gas with diffusion processes and rate reaction is applied to onedimensional unsteady motion generated by initial non-uniformities of state and velocity. The time-dependent system resembles that of steady free mixing of jet or wake type, with two space coordinates. The time-wise character of the profiles of flow variables is studied analytically under two sets of conditions: (1) Zero mass-motion with state non-uniformity in slablike, cylindrical and spherical configurations; this corresponds to steady flow with a nondissipating step-function velocity profile. (2) Mass-motion with uniform temperature in slablike configuration; this corresponds to twodimensional viscous isothermal free mixing with thate variations of concentration and enthalpy. (Author)
