Natural Frequency of 2-dimensional Heaving Circular Cylinder

Effects Of Frequency Variation At Inlet Flow On The Vortex Shedding Frequency Behind A Circular Cylinder

In many applications the flow that past bluff bodies has frequency nature (oscillated) and it is not uniform. This kind of flow has effects on the formation of vortex shedding behind bluff bodies. In this paper the flow around a circular cylinder was numerically simulated. The effects of frequency variation at inlet flow on the vortex shedding frequency were investigated. The transient Two-Dime...

Three-Dimensional Instabilities in the Wake of a Circular Cylinder

Mark Thompson Kerry Hourigan John Sheridan Department of Mechanical Engineering, Monash University, Clayton, Australia • The twoand three-dimensional wake structure behind a circular cylinder has been computed using a high-order spectral element technique. For the two-dimensional computations the predictions are compared with accurate experimental results and agree to within experimental uncert...

Low Frequency Scattering by Circular Dielectric Cylinder: New Polarizability Tensor

This paper considers the low-frequency scattering by a circular dielectric cylinder and modifies the exact polarizability tensor to extend the valid region of the known low-frequency solution. When compared to the traditional formulation, the proposed solution is shown to be valid for cylinders with a higher dielectric constant and larger radius. key words: low frequency scattering, polarizabil...

Diffraction theory of an anisotropic circular cylinder.

A fully analytical theory is developed to derive the field diffracted by an infinitely long circular cylinder made of an arbitrary anisotropic homogeneous material, illuminated by an arbitrary plane wave.
