Abstract:

An investigation of the effect of body forces on a onedimensional, unsteady flow of a reacting gas is presented. The model proposed for this study is that employed by Sforza and Bloom i.e. a central region of gas is perturbed from the state and flow reference values of the ambient and the subsequent temporal and spatial variations of the imposed perturbations are studied analytically. In the present report the configuration of the perturbed region is taken to be slablike this corresponds to a steady two-dimensional jet-orwake-like flow. Results indicate that the effect of buoyancy forces on the velocity field is inversely proportional to the amount of energy absorbed in the chemical relaxation process. In particular, solutions for the case of very small chemical energy absorption become unbounded with time within the present approximation. Author
