Vortex-Induced Vibration Characteristics of an Elastic Circular Cylinder
A numerical simulation of vortex-induced vibration of a 2-dimensional elastic circular cylinder with two degree of freedom under the uniform flow is calculated when Reynolds is 200. 2-dimensional incompressible Navier-Stokes equations are solved with the space-time finite element method, the equation of the cylinder motion is solved with the new explicit integral method and the mesh renew is ac...
متن کاملA Dual -‐ Mesh Framework for Turbulence Modeling : Application to Flow Around a Circular Cylinder
To overcome this difficulty, various hybrid LES/RANS approaches have been developed, where RANS (Reynolds-averaged Navier-Stokes) equations are solved in the near-wall region while LES is only conducted in the free-shear region away from the wall [Fröhlich and von Terzi 2008]. One of the methods to address this issue is a consistent framework for turbulence modeling, where the filtered and Reyn...
متن کاملDrag Coefficients of a Long Flexible Circular Cylinder with Wake Interference
Drag coefficients of the downstream cylinder in a tandem arrangement of two models aligned with the flow are shown in this work. The models. which experienced vortex-induced vibrations with wake inteiference. had an external diameter of 16 mm and a total length of 1.5 m giving an aspect ratio of about 94. More than 400 runs were carried out in a water flume with only the lower 40% of the models...
متن کاملDiffraction 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.
متن کاملexperimental investigation of the characteristics of the wake of a rotating circular cylinder at different reynolds numbers and speed ratios
in this study, the characteristics of the wake around a rotating circular cylinder have been investigated experimentally. to this end, a cylinder with a circular cross-section of plexiglas with the length of 400 mm and a diameter of 20 mm have been tested in the wind tunnel. using existing methods, the characteristics of the wake and the drag coefficients of the model in different cases have be...
