Effect of aspect ratio on the propulsive performance of tandem flapping foils
N. S. Lagopoulos, G. D. Weymouth, B. Ganapathisubramani
In this work, we describe the impact of aspect ratio (AR) on the performance of optimally phased, identical flapping flippers in a tandem configuration. Three-dimensional simulatio…
Deflected Wake Interaction of Tandem Flapping Foils
N. S. Lagopoulos, G. D. Weymouth, B. Ganapathisubramani
Symmetric flapping foils are known to produce deflected jets at high frequency-amplitude combinations even at a zero mean angle of attack. This reduces the frequency range of usefu…
Universal scaling law in drag-to-thrust wake transition of flapping foils
N. S. Lagopoulos, G. D. Weymouth, B. Ganapathisubramani
Reversed von Kármán streets are responsible for a velocity surplus in the wake of flapping foils, indicating the onset of thrust generation. However, the wake pattern cannot be pre…
