Abstract
The solution of the problem of the spatial hypersonic flow of a viscou s gas past spherically blunted bodies is considered using the system o f equations of a complete viscous shock layer (CVSL), The use of the s mall-parameter method (SPM) in conjunction with the method of global i terations enables one to reduce the computer time required by a factor of approximately 100 compared with the time needed to calculate simil ar problems in a strictly spatial formulation by establishment methods [1]. The flow past blunt cones and bicones of long length at low angl es of attack is considered as well as the flow past a body, which diff ers slightly from an axisymmetric one, at zero angle of attack. The ap plicability of the SPM is confirmed by comparison with experimental an d computed data.
