Wake/shear layer interaction for low-Reynolds-number flow over multi-element airfoil

Wake-induced transition in the low-Reynolds-number flow over a multi-element airfoil

“…(2018 a ) and Wang et al. (2018 b ). The measurements are conducted using an aluminum 30P30N multi-element airfoil with a stowed chord length ( c ) and span of 150 and 500 mm, respectively.…”

“…The wake–shear layer interactions over a 30P30N multi-element airfoil have been explored within the low-Reynolds-number range of 8.32 × 10 3 ≤ Re c ≤ 3.05 × 10 4 (Wang et al. 2018 a , b ). Wang et al.…”

“…These Görtler vortices strongly affected the leading-edge separated shear layer of the main element by triggering streamwise streaks inside it. Subsequently, Wang et al (2018 b ) explored the effects of Reynolds number on the wake–shear layer interactions over the front part of the main element ( α = 4°). Two types of wake–shear layer interactions, divided by a critical interval of 1.27 × 10 4 < Re c < 1.38 × 10 4 , were captured within the Re c range of 9.3 × 10 3 to 3.05 × 10 4 .…”

Aerodynamics of the turbulent flow around a multi­element airfoil in cruse configuration and in takeoff and landing configuration

“…Mathematical modeling of the turbulent flow around multi-element airfoils is a rather difficult task of computational aerodynamics [4,5]. Many publications in the modern scientific literature attempt to solve this problem [6][7][8][9][10][11][12][13].…”

“…Experimental work [12] employed anemometry based on the particles images to investigate the interaction between vortexes that descended from the slat and the boundary lay-er at the main profile. The study was conducted at low Reynolds numbers of 9.3×10 3 -3.05×10 4 .…”
