Text of Abstract
Fluid flow past a cylinder has been studied extensively both numerically and experimentally, but the problem of a cylinder vibrating in a fluid that is initially at rest has received little attention. We have numerically studied the resonant behaviour of a cylinder vibrating in Newtonian fluids and in shear-thinning fluids described by the Carreau model. These visually captivating images show the complex spatial variation of the velocity, shear rate, and viscosity that results from small-amplitude vibrations of a cylinder in a shear-thinning fluid.
