Theory and Experiments on Chemical Instabilities.
Abstract
Progress has been made in both experimentation and theoretical studies on chemical instabilities. Some measurements are reported on the dependence of the dynamics of the dynamics of the oscillatory combustion of acetaldehyde in a CSTR upon reactant input rates. Under our conditions, the period of the oscillation is found to be more strongly dependent upon the acetaldehyde input rate than the oxygen input rate. These results are compared with calculations made with a five-variable, twelve-step model. We have made extensive studies of the combustion of acetaldehyde under cool flame conditions in regions of external temperature of the reaction vessel, the pressure and stirring rates of the reacting mixture in the vessel. We have mapped out periodic, quasi periodic and chaotic regions of temporal variations of concentrations, correlation functions, distributions of periods of oscillations, and the so called Procaccia-Grassberger technique. Keywords: Oscillatory Reactions, Chemical Instabilities, Rate Processes, Acetaldehyde, Combustion.
