Analysis of the Equation of the Balance of Energy in the Field of Heating Limited to the Longitudinal Coordinate

Abstract

The analysis of energy balance equation for viscous laminar flow of fluid or gas in the cylindrical channel in the area (zone) of warm up bounded along the longitudinal coordinate is made. It was found that at laminar flow of fluid or gas in a round pipe, in each warm up area bounded along the longitudinal coordinate there are the areas of direct and reverse flows separated by a plane that is a locus of points where temperature is maximal for each fixed value of radial coordinate r. The received results also explain occurrence of returnable currents in plasma of the high-frequency induction discharge of atmospheric pressure.
