Unsteady dynamics in the streamwise-oscillating cylinder wake for forcing frequencies below lock-on
نویسندگان
چکیده
Forcing a cylinder in the streamwise direction with frequency much lower than stationary shedding significantly alters wake dynamics. During certain portions of forcing cycle resembles that cylinder, while others it exhibits strong unsteadiness. Although range flow phenomena are observed, is shown novel time scaling framework can be used to relate forced and unforced systems.

Lagrangian structures and mixing in the wake of a streamwise oscillating cylinder
1 Lagrangian analysis is capable of revealing the underlying structure and complex phenomena in unsteady flows. We present Particle-Image Velocimetry measurements of the wake of a cylinder undergoing streamwise vortex-induced vibrations and calculate the Finite-Time Lyapunov Exponents (FTLE) in backward-and forward-time. The FTLE fields are compared to the phase-averaged vorticity fields for th...
متن کاملVelocity Characteristics in the Wake of an Oscillating Cylinder
This thesis describes the results of over 2000 experimental runs conduced at the MIT Ship Model Testing Tank. A rake of constant temperature anemometers is employed to study the spanwise velocity correlation and the vertical velocity profile downstream of a vibrating cylinder. Experiments involve either free vibration implemented through a force feedback system or forced sinusoidal motion. All ...
متن کاملNonlinear spacing and frequency effects of an oscillating cylinder in the wake of a stationary cylinder
Nonlinear responses to a transversely oscillating cylinder in the wake of a stationary upstream cylinder are studied theoretically by using an immersed-boundary method at Re=100. Response states are investigated in the three flow regimes for a tandem-cylinder system: the “vortex suppression” regime, the critical spacing regime, and the “vortex formation” regime. When the downstream cylinder is ...
متن کاملThe Study of Kinematics and Dynamics of Oscillating Laminar Flow About a Cylinder
In this paper, the oscillating two-dimensional laminar flow about a cylinder and the oscillation of a cylinder in still water are studied. A finite volume method is applied to solve the Navier Stokes equations using SIMPLEC algorithm on a body fitted co-located O-type grid. In this study, the non-dimensional flow numbers, Keulegan-Carpenter and Stokes’ numbers are chosen over a range where diff...
متن کاملThe onset of chaos in the wake of an oscillating cylinder: Experiment and the dynamics of the circle map
This paper deals with a comparison between experimental observations in a lowReynolds-number wake behind an oscillating cylinder and the universal properties of a sine circle map. When the limit cycle due to the natural vortex shedding in the wake is modulated at a second frequency by oscillating the cylinder transversely, one obtains in phase space a flow on a two toms. The nonlinear interacti...
