ESTABLISHING THE NATURE OF KINETIC EFFECTS OF THE HIGH TEMPERATURE OXIDATION (COMBUSTION) PROCESS OF SOME LIQUID ORGANIC MATTERS BY ACOUSTIC RADIATION

Abstract

In this article the physicochemical characteristics effect researching results of some liquid organic matters (OM) on the kinetics of their high-temperature oxidation (combustion) were presented for the first time. These results were obtained by the method of acoustic emission spectrum from heat source. The research results of the amplitude-time characteristics (until cessation of combustion completely) and the frequency response functions (in a given frequency range) of oxidation (combustion) process of liquid OM showed an unambiguous dependence: 1) the number in a given frequency range, of the amplitude maximum of the frequency and time spectrum, as well as of the fractal dimension received acoustic signal on the number of carbon atoms in the carbon frame of OM and their molar mass; 2) the time beginning of combustion (ignition) primary cloud of OM vapors and the final combustion time of the primary cloud of OM vapors from the number of carbon atoms in the carbon frame of the OM and the OM partial pressure vapors. The practical aspect of using the results obtained is dictated by the need to develop standard samples of amplitude-time and amplitude-frequency characteristics, depending on the physicochemical and combustible properties of the OM. That is necessary for the data bank of the acoustic emission monitoring system to establish a fire hazardous state and make anti-crisis decisions at critical infrastructure facilities.
