On the electrostatic field in expansion dynamics of gas bubbles

Abstract

The work is devoted to the study of the dynamics of the formation ofbubbles in a gas–liquid system taking into account the potential difference.The electrical conductivity of the fluid is determined depending on theconcentration of the electrolyte and, accordingly, the electrostatic field thatoccurs when the fluid flows. The effect of the electrostatic field on the bubbleformation dynamics has shown that the radius of the gas bubbles and thedynamics of its expansion, formed by the pressure difference, can be regulatedby the potential difference parameter. Depending on the electrolytic concentration,the electric conductivity of the liquid and, accordingly, the electrostatic fieldarising from friction in fluid are determined. The effect of the electrostaticfield on the dynamics of the bubble formation has shown that the radius ofgas bubbles and expansion dynamics formed by the pressure drop can beregulated by the potential difference parameter. It is presented that one of themain factors affecting the flow of two-phase fluids is the nature of the liquidphase and the concentration of electrolyte added. The results of regulation ofthe bubble formation dynamics in the gas–liquid system via the electrostaticfield and a number of physical parameters can be applied in the oil and gasindustry, chemical processes, biomechanics.
