Simulations of flow around a confined oscillating circular cylinder using a virtual boundary method
(2003) Second International Conference on Fluid Structure Interaction, FLUID STRUCTURE INTERACTION II 36. p.343-352- Abstract
- In this paper streamwise and transverse oscillations of a rigid circular cylinder in a rectangular channel are investigated using the Virtual Boundary method. Numerical study of the three-dimensional flow around the cylinder is done for the uniform Cartesian grid. All computations are performed at Reynolds numbers of Re=500 and 1000 based on the mean flow velocity. The Keulegan-Carpenter number (Kc) of cylinder forced oscillation is equal to 6 and the excitation frequencies considered are higher, lower and equal to the vortex shedding frequency. The locked-on state of the wake for the transverse and streamwise oscillations of a cylinder in uniform flow are obtained. The force coefficients spectra show the presence of a dominating component... (More)
