The stability of low-amplitude three-dimensional disturbances in a nonequilibrium compressible boundary layer
I. P. Zavershinskii, V. N. Knestyapin S. P. Korolyov Samara State Aerospace University
Abstract:
The stability of Tollmien-Schlichting waves propagating at an angle to the main flow in a nonequilibrium compressible supersonic boundary layer is investigated within the linear theory of hydrodynamic stability. The dependences of the critical Reynolds number on the degree of disequilibrium and on the Mach number of undisturbed flow are found at different angles of wave propagation. It is demonstrated that the critical Reynolds number in a nonequilibrium medium may decrease appreciably with increasing degree of disequilibrium, which results in the reduction of the characteristic length of the linear region of transition to turbulence.
