On the transition of the cylinder wake
Web22 de mar. de 2024 · Some studies have also analyzed various nuances of the flow-field during aperiodic/chaotic transitions in the wake of flapping foils. Small time-delay in the formation and growth of the primary leading-edge-vortex (LEV) in successive cycles were reported to be the very first trigger for aperiodicity ( 2 , 5 , 9 ). Web7 de jan. de 2024 · The progressive wake transition to chaos is found to originate from the instability in the braid shear layer region through the uneven growth in strength and the consequent nonuniformity of the …
