Heat transfer and resistance in the pipe flow of a dissociating gas
Abstract
The paper considers turbulent flow and heat transfer of a multicomponent chemically reacting gas mixture in a pipe; consideration is given to the mutual interaction of chemical reactions and turbulence, diffusion separation, the nonequilibrium character of chemical reactions, and the variability of the physical and chemical properties of the mixture. Attention is given to the effect of turbulent fluctuations of temperature and composition on the magnitude of the chemical source and the heat transfer intensity in the case of the pipe flow of a binary dissociating mixture. A balanceequation method for determining the effect of chemical nonequilibrium on turbulent fluctuations of temperature and composition is presented.
