The interaction between a strong longitudinal vortex and a turbulent boundary layer

摘要: This paper presents the preliminary results of a long-term investigation interaction strong longitudinal vortices with turbulent boundary layers. A pair trailing is generated by delta wing, which mounted ahead flat plate so that merge layer on upper surface plate, while non-rolled-up part delta-wing wake passes below plate. approximates an aircraft wing close-coupled canard. The measurements show how boundary-layer fluid first subjected to large cross flow and then transported away from circulate around vortex core.
