Numerical simulation of VIV for an elastic cylinder mounted on the spring supports with low mass-ratio
VIV low mass ratio stream-wise and transverse motion two-degree-of-freedom vortex shedding model CFD
2011/9/13
With the development of the offshore deep water oil industry many researchers are focusing on the vortex-induced vibrations (VIV) of deep risers. In the present work, Reynolds–averaged Navier–Stokes (...
Three-dimensional numerical simulation of the flow past a circular cylinder based on LES method
LES method three-dimensional flow past circular cylinder hydrodynamic characteristics
2011/9/13
The hydrodynamic characteristics of a rigid, single, circular cylinder in a three dimensional, incompressible, uniform cross flow were calculated using the large-eddy simulation method of CFX5. Soluti...
On the Cylinder Collapse Problem, Mixing, and the Merger of Isolated Eddies
Cylinder Collapse Mixing Merger Isolated Eddies
2008/12/30
The Rossby adjustment of an initially circular column of water, the so-called collapse of a cylinder, continues to be a widely used method for forming lenslike eddies in the laboratory. Here, we consi...
The Time-dependent Collapse of a Rotating Fluid Cylinder
angular momentum ocean circulation Rotating Fluid Cylinder
2008/12/22
The behavior of a reduced-gravity cylinder of fluid, released from rest in a rotating system, is considered. The eventual steady state, found by normal principles of conservation of angular momentum, ...
Flow past a Cylinder on a β Plane, with Application to Gulf Stream Separation and the Antarctic Circumpolar Current
Gulf Stream Separation Antarctic Circumpolar Current
2008/7/25
The classical problem of flow past a cylinder is revisited in the context of understanding two oceanographic phenomena: separation of the Gulf Stream from the North American coastline at Cape Hatteras...
