Passive Control of Shock Oscillation Around a Biconvex Circular Arc Airfoil in a Channel

Passive jet control of flow around a circular cylinder

and suppressing fluctuating amplitude of the dynamic wind loads acting on the test model. With 24 suction/jet holes evenly distributed over the cylindrical test model (i.e., the N13 design of the present study), the passive jet control method was found to be able to achieve up to 33.7 % in drag reduction and 90.6 % in fluctuating wind loading suppression, in comparison with the baseline case.

Flow Visualization Around a Non - Circular Tube

The flow behavior around a cam shaped tube in cross flow has been investigated experimentally using flow visualization and pressure distribution measurement. The range of attack angle and Reynolds number based on an equivalent circular diameter are within 0 ≤ α ≤ 360˚ and 2 x 104 < Reeq < 3.4 x 104, respectively. The pressure drag features are clarified in relation to the flow behavior around t...

a parametric study for passive control of shock-boundary layer interaction of an airfoil with porous media in a transonic flow

shock formation due to flow compressibility and its interaction with boundary layer has inappropriate effects, such as drag increase and flow separation. many methods have been proposed for reduction of these effects, such as vortex generator, suction, and blowing. this paper numerically studies the problem of flow control for naca0012 airfoil with porous media at transonic flow. porous media, ...
