Application of the small-parameter method to the problem of the spatial flow of a viscous gas past bodies

The solution of the problem of the spatial hypersonic flow of a viscous gas past spherically blunted bodies is considered using the system of equations of a complete viscous shock layer (CVSL). The use of the small-parameter method (SPM) in conjunction with the method of global iterations enables one to reduce the computer time required by a factor of approximately 100 compared with the time needed to calculate similar problems in a strictly spatial formulation by establishment methods [1]. The flow past blunt cones and bicones of long length at low angles of attack is considered as well as the flow past a body, which differs slightly from an axisymmetric one, at zero angle of attack. The applicability of the SPM is confirmed by comparison with experimental and computed data. © 1993.
