Incompressible Laminar Flow Past a Transversely Vibrating Cylinder

Abstract: An implicit finite difference scheme in primitive variables is used for analysis of unsteady, laminar flow past transversely vibrating cylinders. Predictions of flow past an impulsively started cylinder and of vortex shedding from a stationary cylinder agree well with experimental data. Calculations of flow past a transversely vibrating cylinder were within the range of experimental scatter only for small vibration amplitudes. Several experimentally observed phenomena such as drag amplification and reduction i… Show more

“…Some similar results have been obtained by other authors-Chilukury [9], for instance, reports C LI :0.62 for Re= 144, F m =St and Y 0 /D=0.14, and also indicates, for Re= 80 and Y 0 /D =0.14, a slight increase in drag for F m =St (about 12% with respect to the steady case), while no drag amplification has been attained in other oscillating cases with F m close to St. (=0.14). These values agree with the experimental ones obtained by Tanida et al [36] for the same Re ( =80).…”

“…The values obtained in this situation for the drag amplification and for the phase shift between lift and motion are similar to the CFD results reported by Hurlbut et al [8] and by Chilukuri [9]. In order to investigate the influence of the driving frequency on the spacing of the vortices in the wake at locked-in conditions, and to compare it with the fixed situation, the streamlines and the fluid pressures obtained near the cylinder at an instant of maximum upwards lift in the fixed case and at instants of uppermost position in the oscillating cases are plotted in Plates 1 and 2.…”

“…These downstream boundary conditions have only a weak influence on the flow field, which was verified by changing the distance between the cylin- der and the downstream boundaries (Chilukuri, 1987). A downstream distance of 40.0 away from the cylinder is chosen as the outflow computational boundary.…”
