Airfoils work because the higher speed of air going over the top surface results in lower air pressure than the slower air beneath. If you drilled a hole top to bottom in an airfoil, which direction ...

Abstract: The study of an airfoil at low Reynolds number regime was found to be a typical problem where the inception of bifurcations leads the flow evolution from a stationary or periodic behaviour ...

A. Flow without flow separation and with flow separation. B. Pressure distribution trend without flow separation and with flow separation. To prevent aircraft stalls, engineers have long studied the ...

Natural laminar flow is a known means of reducing aircraft drag and energy consumption, but its practical implementation is difficult on commercial airliners that cruise at transonic speeds and ...
