Equilibrium configuration of a rectangular obstacle immersed in a channel flow
Denis Bonheure (Université Libre de Bruxelles)
Abstract: Fluid flows around an obstacle generate vortices which, in turn, generate lift forces on the obstacle. Therefore, even in a perfectly symmetric framework equilibrium positions may be asymmetric. We show that this is not the case for a Poiseuille flow in an unbounded 2D channel, at least for small Reynolds number and flow rate. We consider both the cases of vertically moving obstacles and obstacles rotating around a fixed pin. Joint work with P.G. Galdi and F. Gazzola
