An Investigation on the Flow Behavior in the Airfoil of a Flapping Wing

In this investigation, the two-dimensional dynamic analyses of the wing airfoil of a swing-wing micro air vehicle (MAV) were carried under restrained pitching and flapping oscillations, which varied in the 10-degree oscillation range and the 0.1-10 reduced frequency range. The flow was in a laminar flow with a Reynolds number of 1100. The objective of this simulation was to study the flow behavior in the dynamic motions in a dynamic stall regime. Similar studies on the dynamic stall regime with low Reynolds numbers have not resulted in a particular numerical solution and have separately studied the parameters influencing the numerical solution. The most critical dynamic motions that require utmost precision in numerical analyses were reviewed and validated in this research. The results of the numerical research analyses were compared to the experimental results obtained with a water tunnel.
