Abstract

We simulate flow past a circular cylinder undergoing inline oscillations. Over some ranges of amplitude and frequency of oscillations, synchronization takes place and yields a significant reduction in the lift coefficient. We identify the synchronization region by exploring the parameter space through a global optimizer. The results show that this tool can find the synchronized region after a small number of function evaluations.
