Abstract

âº Lock-on wake characteristics behind side-by-side unequal cylinders are studied. âº Gap and diameter ratios are 0.75 and 2.0. The Reynolds number is 600. âº Wake of large cylinder experiences the primary and one third sub-harmonics lock-on. âº While lock-on, the gap vortices entrain alternately into the wake of each cylinder. âº The lock-on synchronizes with the fundamental or one third of excitation frequency.
