Aerodynamic characteristics and thermal responce of blunt-nosed bodies being flown about by rarefield gas

Subject of inquiry: hypersonic flow about blunt-nosed bodies under transient condition from free-molecular to continuous medium condition. The aim of the work is to obtain heat flows and flow fields local values; to study influence of blow-in, sphere rotation, cylindrical edge slip angle upon flow around characteristics. Gravimetric methods of direct statistical modelling were applied in solving flow about problems. Gravimetric modification of the most efficient scheme of space-homogeneous relaxation has been offered. Local values of heat flows on blunt-nosed bodies have been obtained within the expanded range of reynolds numbers. A damping moment acting on the rotatable sphere under transient conditions has been analysed. An applicability range for a model of thin viscous impact layer has been determined. The results of the work are the basis for elaborating engineering design methods concerning aerodynamic characteristics and thermal responce. Data about heat transfer is included into 'Vysota-2' applied program part being utilized at a number of Aircraft Industry Scientific-Research Institutes and Design OfficesAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
