Abstract

In scientific work investigates the impact of electric fields on combustion of hexamine. The experimental setup has been developed to study the interaction of an electric field with a low-temperature flame. The optimal spatial configuration of the electrodes for extinguishing the flame was established; the dynamics of airflows caused by the ion wind was studied; the threshold value of the electric field leading to flame extinguishing was determined. An expression is proposed based on the equation of motion that connects the speed of motion of partially ionized gas particles, the viscosity and degree of ionization of the gas, and the intensity of the external electric field. It is shown that the strength of the external electric field, leading to extinguishing of hexamine combustion, increases with decreasing inter-electrode space. The values of corresponding electric field strength lied in range from 80 to 135 kV/m at interelectrode distances of 0.4 and 0.1 m, respectively. The results of the study can be used for effective fire extinguishing in compact devices running on dry fuel.
