  • Vortex shedding suppression and wake control: A review
    In this survey, existing studies on different methods of controlling the wake destructive behavior and suppression of vortex shedding behind bluff bodies are discussed, including the very recent developments These methods are classified into two groups
  • Vortex shedding - Wikipedia
    In fluid dynamics, vortex shedding is an oscillating flow that takes place when a fluid such as air or water flows past a bluff (as opposed to streamlined) body at certain velocities, depending on the size and shape of the body
  • FUNDAMENTALS OF VORTEX-INDUCED VIBRATION - Bureau of Safety . . .
    physics of a steady approach flow past a nonvibrating circular cylinder • How and why does VIV occur? • What kind of body shapes experience VIV? • What kinds of VIV are there? o Self-excited oscillations - this type of VIV is what occurs naturally, i e , when the vortex-shedding frequency and the natural frequency are approximately the same
  • Vortex Shedding - fedele. gatech. edu
    Vortex shedding is a phenomenon that occurs when the current flow of a body of water is disrupted by an obstruction, in this case a bluff body When placed in a fluid flow most bodies create a separated flow across a substantial proportion of their surface, thus classifying them as bluff (Bearman)
  • Vortex Shedding 101: What is it Why Does It Matter?
    The physics of vortex shedding in piping is exactly the same as wind passing around a car antenna or atmospheric vortex shedding from an island When you have fluid flowing over an object, it will produce oscillating flow vortices, and those oscillations can cause fluctuations in the pipe
  • Characteristics of vortex shedding in the wake of a sphere . . .
    These studies showed that wakes can be controlled through the creation of vents on bluff bodies and through changes in the vent angle, which have been demonstrated to affect the vortex shedding frequency and vortex size
  • Review—Vortex Shedding Lock-on and Flow Control in Bluff Body . . .
    This form of vortex shedding and lock-on exhibits a particularly strong resonance between the flow perturbations and the vortices, and provides one of several promising means for modification and control of the basic formation and stability mechanisms in the near-wake of a bluff body
