Bifurcation theory for three-dimensional flow in the wake of a circular cylinder
نویسندگان
چکیده
A bifurcation scenario is presented for three-dimensional vortex shedding in the wake of a circular cylinder for Reynolds numbers up to 300. Amplitude equations are proposed to describe the nonlinear interaction between two three-dimensional modes of shedding with different spanwise wave numbers and different spatiotemporal symmetries. The amplitude equations explain many features of the transition scenario observed experimentally.

A coupled Landau model describing the Strouhal–Reynolds number profile of a three-dimensional circular cylinder wake
A known bifurcation scenario describing the development and interaction of Mode A and Mode B vortex shedding modes of a circular cylinder wake is extended to predict the Strouhal–Reynolds number profile over the three-dimensional transitions. The mode amplitudes are described by coupled Landau equations and, with frequency information being included by the addition of complex coefficients, the ...

This research describes the unsteady two-dimensional reacting flows around a circular cylinder. The numerical solution combines the random vortex method for incompressible two-dimensional viscous fluid flow with a Simple Line Interface Calculation (SLIC) algorithm for the propagation of flame interface. To simplify the governing equations, two fundamental assumptions namely Low Mach Number and ...
متن کاملSTABILITY THEORY FOR THREE - DIMENSIONAL WAKETRANSITIONDwight
A nonlinear stability theory is presented for three-dimensional transition in the wake of a circular cylinder up to Reynolds number 300. The primary input to the theory is the linear and the nonlinear stability results of Barkley and Hen-derson. Based on symmetric bifurcation theory, normal form equations are proposed to describe (to lowest order) the nonlin-ear interaction of three-dimensional...
متن کاملExperimental investigation for wake of the circular cylinder by attaching different number of tripping wires
An experimental study is conducted on flow past a circular cylinder fitted with some tripping wires on its surface. The work investigates the dependency of the critical wire locations on the wire size and Reynolds numbers, and examines the wake and vortex shedding characteristics in an effort to advance the understanding of the critical wire effects beyond the existing literature. The primary a...
متن کاملStability and Bifurcation Analysis of a Forced Cylinder Wake
We present a study on the dynamics of a cylinder wake subjected to forced excitation. Williams et al. (1992) discovered that the spatial symmetry of the excitation plays a crucial role in determining the resulting wake dynamics. Reflection-symmetric forcing was found to affect the Karman wake much more strongly compared to 2 ( , ) Z κ π asymmetric forcing. For low forcing amplitudes, the existe...
