Scaling of secondary flows with surface parameters: a linear approach
Gerardo Zampino, Davide Lasagna, Bharathram Ganapathisubramani
Secondary flows are generated when a lateral variation of the topography, such as streamwise aligned ridges, is imposed to a turbulent wall-bounded flow. In this case, the flow fie…
Effects of Aspect Ratio on Rolling and Twisting Foils
A. N. Zurman-Nasution, B. Ganapathisubramani, G. D. Weymouth
Flapping flight and swimming are increasingly studied both due to their intrinsic scientific richness and their applicability to novel robotic systems. Strip theory is often applie…
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…
On the decay of dispersive motions in the outer region of rough-wall boundary layers
Johan Meyers, Bharathram Ganapathisubramani, Raúl Bayoán Cal
In rough-wall boundary layers, wall-parallel non-homogeneous mean-flow solutions exist that lead to so-called dispersive velocity components and dispersive stresses. They play a si…
Law-of-the-wall for streamwise energy spectra in high-Reynolds-number turbulent boundary layers
B. Ganapathisubramani
A scaling relation for the high frequency regime of streamwise energy spectra (in frequency domain) in the near-wall region is proposed. This is based on the dimensional analysis a…
