Natural Frequency of 2-Dimensional Heaving Circular Cylinder: Frequency-Domain Analysis

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...

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...

Performance Analysis of Radar Target Recognition Using Natural Frequency: Frequency Domain Approach

We consider the performance analysis of natural frequency-based radar target recognition in the frequency domain. Based on the probability density function (PDF) of some quantity consisting of the projections of the frequency response onto the column spaces of the matrices constructed using the natural frequencies of the specific targets, we propose to analytically calculate the probability of ...

Frequency-Domain Harmonic Analysis Methods

There are a large number of frequency-domain analysis methods that are in widespread use. The most popular of these are frequency scans, harmonic penetration, and harmonic power flow. Each of these techniques can be employed on a “per-phase” (positive or zero sequence) or “multi-phase” basis and each technique utilizes an admittance matrix system model developed from individual component-level ...
