Influence of Chemical Reactions in a Boundary Layer on the Overall Heat-and-Mass Transfer Coefficient
Abstract
A method to analyze the influence of chemical reactions on heat-and-mass transfer in a reactive boundary layer has been suggested, and the influence of thermal effects on the overall heat-and-mass transfer coefficient has been estimated. It has been found that endothermal reactions in the boundary layer have a considerable effect on the overall heat-and-mass transfer coefficient. Taking into account the influence of thermal effects due to homogeneous reactions inside the boundary layer on convective thermal flux \({{\dot {q}}_{\lambda }}\) is equivalent to taking into account the heat of these reactions on the surface of a heat protection coating, that is, on the surface of a coked layer.
期刊介绍：
High Temperature is an international peer reviewed journal that publishes original papers and reviews written by theoretical and experimental researchers. The journal deals with properties and processes in low-temperature plasma; thermophysical properties of substances including pure materials, mixtures and alloys; the properties in the vicinity of the critical point, equations of state; phase equilibrium; heat and mass transfer phenomena, in particular, by forced and free convections; processes of boiling and condensation, radiation, and complex heat transfer; experimental methods and apparatuses; high-temperature facilities for power engineering applications, etc. The journal reflects the current trends in thermophysical research. It presents the results of present-day experimental and theoretical studies in the processes of complex heat transfer, thermal, gas dynamic processes, and processes of heat and mass transfer, as well as the latest advances in the theoretical description of the properties of high-temperature media.
