Supersonic laminar separated flow structure at a ramp for a free-stream mach number of 6

Abstract: A three-dimensional (3D) structure of a separated §ow in a compression corner at a free-stream Mach number í = 6 is studied. The model is a §at plate with an almost sharp leading edge on which a 30 • ramp is mounted. The spanwise size of the model is equal to the length of the plate from the leading edge to the ramp. The angle of attack is varied from 0 • to 15 • . The shock wave structure of the §ow near the model is shown. The existence of a thin high total pressure layer (dynamic layer) is found. The dynami… Show more

“…However, in most compression ramp studies, the comparison with the theory of Görtler instability on curved walls is only qualitative. Furthermore, this theory does not account for the amplification that arises from baroclinic effects in the presence of the wall-normal density gradients (Zapryagaev, Kavun & Lipatov 2013) and most of the literature neglects the dynamics in the separation bubble. Zhuang et al.…”

“…The flow structure near the separation and reattachment regions is investigated using both the experimental data (visualization of the flow pattern and the limiting streamlines on the model surface, the pressure distribution along the axis of symmetry of the model, and the measurements of the total pressure profile) and the results of the numerical calculations of an unsteady three-dimensional laminar flow. The study continues an investigation of the shock-wave structures in separated laminar supersonic flows [5]. 820 ZAPRYAGAEV et al …”

“…Исследования взаимодействий ударных волн с пограничными слоями активно ведутся во всем мире, начиная приблизительно с окончания Второй мировой войны. Несмотря на огромный объем полученных результатов [1][2][3][4][5][6][7][8][9][10][11][12], многие вопросы требуют дальнейших исследований и привлекают пристальное внимание ученых в РФ и за рубежом. В настоящее время эти исследования приобретают особую актуальность в связи с разработкой в РФ и за рубежом прямоточных реактивных двигателей (ПВРД) для гиперзвуковых летательных аппаратов [8].…”
