Viscoelastic flow-induced oscillations of a cantilevered beam in the crossflow of a wormlike micelle solution

We investigate the interactions between a cantilevered flexible beam and cross-flow of a viscoelastic fluid. Unlike Newtonian fluids, viscoelastic fluids exhibit elastic flow instabilities even in the absence of inertia. These elastic flow instabilities drive the oscillations of flexible structures...
