Abstract
A recently developed numerical method for flows with moving boundaries
is used for simulating the flow-induced vibration of cylinders. The key feature of
the numerical method is that it allows us to simulate flows with moving
boundaries on stationary Cartesian grids. In this paper we briefly describe the
computational methodology. The method is used to simulate (a) transverse flowinduced
vibration of a cylinder in a freestream where the computed results are
compared with theory and other simulations and (b) flow-induced vibration of a
cylinder pair where we examine the effect of relative placement of the cylinders
on the vibration of the two cylinders. Results of these simulations are also
presented.
