Abstract
The heat and mass transfer between the dissociating boundary layer and the surface of blunt nose cones of high-speed aircraft in a wide range of Mach numbers is considered. Using Dorodnitsyn–Liz variables, the system of boundary layer equations is reduced to a system of nonlinear ordinary differential equations. Using reasonable assumptions, approximate analytical solutions were obtained for dynamic, thermal, and diffusion boundary layers, which made it possible to determine thermal and diffusion heat fluxes, which at the gas–solid boundary are coupled with the equation of heat conduction in the body with the coupling parameter being the temperature of the gas–solid boundary. From the found heat fluxes, the temperature fields in the body were determined in a wide range of free-stream Mach numbers and the catalytic recombination coefficient. The resulting heat fluxes on the frontal part of the nose cone exactly coincide with the experimental data.
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.
