Abstract

![CDATA[Flow around a rotating circular cylinder at a Reynolds number of 500 is investigated numerically. The aim of this study is to investigate the effect of high rotation rate on the wake flow past a circular cylinder. Simulations are performed at a constant Reynolds number of 500 and a wide range of rotation rate from 1.6 to 6. Rotation rate is the ratio of the rotational speed of the cylinder surface to the incoming fluid velocity. It is found that increasing rotation rate beyond a critical value results in transition from no vortex shedding regime to secondary instability regime where the oscillation of the lift force on the rotating cylinder increases drastically. This secondary instability regime was also observed at low Reynolds number where the flow is laminar.]]
