Title : Investigation of weak shock waves in reactorsunder oxidation of propane and experimental evidence for the presence of a saddle-type singular point in the reactor center
Abstract:
The explanation of registration of pulsating light emission from a reactor during low-temperature oxidation of organic compounds, as a consequence of the birth of weak shock waves in the surface layer of the reactor, is considered. Their birth, as shown in our early works, is due to the rapid conversion of the intermediate product H2O2 into ozone molecules, the cause of which is the presence of negative chlorine ions at the surface. A well-known self-similar method is used to assert that a special point saddle can be present in the system. The property of being reflected from the surface, as well as the property of a special point saddle, reflecting weak shock waves leads to a situation when both the periphery and the center of the reactor reflect a weak shock wave. Under these conditions, as a rule, there are closed trajectories on which the trajectory of the shock wave is wound. As a result, the radiation of this wave, which is born in the combustible mixture, becomes detectable. Experimental registration of weak shock waves in the reactor is given.
