Abstract: In this study, the flow features of vortex shedding from a pair of parallel arranged circular cylinders of unequal diameter oscillating along the direction of the flow were observed by visualizing water flow experiment at the ranges of the frequency ratio f/f K =0~7, amplitude ratio 2a/d=0.125, 0.25, 0.5 and 0.75, gap ratio G/d=0.25, 0.75 and 1.75, diameter ratio d'/d=0.25 and 0.5 and Reynolds number Re=500. The variations of mean vortex shedding frequency from oscillating cylinder were investigated. As a resu… Show more
