Characteristics of laminar-turbulent boundary layer transition on a cone

The effect of the unit Reynolds number and the Mach number on the transition on a slender circular cone is experimentally investigated. The perturbation spectra in the boundary layer on the cone are measured. It is shown that the location of the transition is determined by the perturbation level at the frequencies causing transition.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 6, pp. 23–27, November–December, 1985.
