Экспериментальное исследование влияния электростатических полей на тепловые процессы в газообразном метане при его естественной конвекции

Abstract

The paper shows the history of studying electrostatic fields in various gaseous media, including gaseous methane, and substantiates the necessity to experimentally study electrostatic fields influencing thermal processes in gaseous methane at its natural convection. We describe the experimental base and working areas with the use of electrostatic fields, as well as the method of conducting experimental research. The results of the influence of electrostatic fields on the coefficient of heat transfer to gaseous methane and on the negative process of sedimentation in it — during its natural convection are presented. In our research, we found zones of possible intensification of heat transfer to gaseous methane and zones of saturation with electrostatic fields, in which a further increase in the heat transfer coefficient is impossible. We experimentally established that the boundary of the zone of the beginning of saturation with electrostatic fields is also the beginning of the corona discharge zone. The research results formed the basis for the method of using electrostatic fields in aircraft engines and power plants.
