Aerothermochemical interaction between a hypersonic flow and surfaces with different geometries

The paper presents theoretical models for aerothermochemical interaction between the streamlined surface and dissociated air for the case of combustion and sublimation near a frontal critical point of a blunt body. The methods and results were generalized for obtaining a solution based on the similarity method for the case of combustion and sublimation. The approach is based on an example of graphite in an arbitrary cross-section of cone, sphere, wedge, cylinder, plate, and a spherical cone for a case of a laminar flow with a high Reynolds number. For a hypersonic flow past bodies with various geometry shapes, calculations for mass flux, heat flux and drag coefficient were presented. The results are linked through universal dependencies expressed through stagnation enthalpy, pressure, velocity gradient, pressure gradient and surface temperature.
