Effects of Cross Cylinders on Aerodynamic Sound from Two Parallel Circular Cylinders

Electromagnetic Scattering from Parallel Chiral Cylinders of Circular Cross- Sections Using an Iterative Procedure

The electromagnetic scattering from a 2D chiral circular cylinders, illuminated by either a TEz or a TMz plane wave, is investigated using an iterative scattering procedure. The developed formulation and the implemented code simulate different types of cylinders, where the cylinders can be made of anisotropic chiral material with uniform or non-uniform chiral admittance distribution, homogeneou...

Parallel 3D Computation of Unsteady Flows Around Circular Cylinders

Cross sections for extinction of tilted infinite circular cylinders.

It follows that Kerker's equations (6.1.46) and (6.1.47) should be deleted, and the quantities C n e x t and C22 ext should be replaced by C1 ex t and C2 ex t . Note that the forwardscattering (θ = 0) wave as well as the backscattering wave from tilted infinite cylinders is not de­ polarized, an effect which is well known in the case of spheres. But in contradiction to the spheres, the followin...

Lower Mode Response of Circular Cylinders in Cross-Flow

Transverse amplitude responses ofa circular cylinder in cross-flow were determined as a function of reduced velocities for a variety of spring constants and damping coefficients. Maxima were found at reduced velocities of 5 and 16, and were of comparable amplitude. The first resonance, designated the "fundamental mode, " was due to normal vortex street excitation of the spring-mass system. The ...

Speeding up the Stress Analysis of Hollow Circular FGM Cylinders by Parallel Finite Element Method

In this article, a parallel computer program is implemented, based on Finite Element Method, to speed up the analysis of hollow circular cylinders, made from Functionally Graded Materials (FGMs). FGMs are inhomogeneous materials, which their composition gradually varies over volume. In parallel processing, an algorithm is first divided to independent tasks, which may use individual or shared da...
