Abstract: | We consider the hypersonic flow of a perfect gas past a slender three-dimensional body in a regime of strong viscous interaction. We give equations which make it possible to reduce the problem of determining the aerodynamic characteristics of a body which is not axisymmetric to the problem of computing the flow past an equivalent body of rotation at zero angle of incidence. The second approximation for the heat transfer and drag coefficients is found by the method of external and internal combinations of asymptotic expansions. The region in which this method can be applied and the accuracy of the asymptotic theory are estimated by comparison with exact numerical computations.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti, i Gaza, No. 5, pp. 107–113, September–October, 1970. |
