Description
Summary:A mathematical and numerical formulation is derived for fluid/structure interaction problems involving arbitrary geometries relevant to the simulation of bridge deck instabilities due to cross winds. A translating and rotating moving frame of reference is attached to the body to utilize an efficient fixed mesh spectral/hp element solver. The formulation is validated against experiments with flow simulations of circular cylinders at Reynolds numbers of 100–400 undergoing free and forced motion in the transverse and in‐line directions. The well‐documented phenomena of vortex lock‐in is captured. The formulation is then applied a rectangular body at Re=250 under forced and free motion the latter of which demonstrates torsional galloping. Copyright © 2002 John Wiley & Sons, Ltd.
