MATHEMATICAL MODELING OF DISSOCIATION AND HEAT EXCHANGE PROCESSES IN A GAS FLOW

A mathematical model of heat transfer processes in a cylindrical channel with a turbulent flow of dinitrogen tetroxide is presented in this paper. Increased wall temperatures enhance chemical reactions in the flow and increase thermal energy absorption. A reacting flow has a lower temperature near the wall than an inert coolant. Studies have shown that increasing flow velocity decreases dissociation. In extended channels, dissociating gas is most efficient at low flow rates. This coolant is ineffective at low wall temperatures.
