Abstract

In this paper we use a newly developed lattice Boltzmann technique to simulate the wake of a streamwise oscillating cylinder in the presence of a downstream stationary cylinder. The oscillating frequency ratio f e /f s , varies between 0 and 1.8, where f e is the oscillating frequency of the upstream cylinder and f s is the natural vortex shedding frequency of an isolated stationary cylinder, and the oscillating amplitude A is fixed at 0.5 cylinder diameter, D. Three typical flow structures, depending on f e /f s and A/D, have been identified at the cylinder center-to-center spacing L/D = 3.5, which are in excellent agreement with experimental data. The lift and drag coefficients on the two cylinders are also examined for each flow structure.
