Resumo

Results of direct numerical simulation of the receptivity of the supersonic boundary layer over an upswept wing with a thin parabolic profile to acoustic noise of various intensity are presented. Acoustic noise is shown to be capable of triggering laminar-turbulent transition over the upswept wing of supersonic transport.

Palavras-chave
