Victor Nosulenko, Prof., DSc., Vitaliy Shmelyov, Assoc. Prof., Phd tech. sci. Centralukrainian National Technical University, Kropivnitsky, Ukraine Features of an electric arc in a cross flow of fluid The paper purpose - Development of theoretical bases of an electric arc in a cross flow of fluid. Studying and the description of features and character of interaction of an arch with a cross flow of fluid. In a paper describes an arc in a cross flow of fluid. Shows the complete system of equations that describes the model of electric arc plasma, moving from the condition that of equality of the temperatures of all her components. Shows frames from high-speed filming burning arc in a cross flow of fluid in conditions of dimensional processing by an electric arc, which moves along the surface of the electrodes, moving in an arc is discrete, that is, the arc after some standing in place moves to another, usually the nearest land, or arises in a different place between the electrodes. Describes an electric arc in a cross flow of fluid as a source of magnetic energy. Described triangle interconversion energy magnetic, power, energy fields. electric arc, magnetic induction, electric field, force field, magnetic field, triangle interconversions, the arc column 13.05.17
