The numerical investigation focuses on the flow patterns around a rectangular cylinder with three aspect ratios ( $L/D=5$ , $10$ $15$ ) at Reynolds number of $1000$ . study delves into dynamics vortices, their associated frequencies, evolution boundary layer and decay wake. Kelvin–Helmholtz (KH) vortices originate from leading edge (LE) shear transform hairpin vortices. Specifically, KH merge single LE vortex. However, $L/D=10$ two combine to form vortex, rapid formation vortex packets. A...
Vortex-induced vibration (VIV) in oscillatory flow is experimentally investigated the ocean basin. The test flexible cylinder was forced to harmonically oscillate various combinations of amplitude and period with Keulegan-Carpenter (KC) number between 26 178 three different maximum reduced velocities, URmax=4, URmax=6.5, URmax=7.9 separately. VIV responses at cross-flow (CF) direction are using modal decomposition wavelet transformation. results show that quite from steady flow; features,...
This paper introduces a new method which is based on multi-body hydrodynamics and Euler–Bernoulli beam assumption to study hydroelastic behaviours of very large floating structures (VLFSs). A continuous VLFS divided into several modules, being multi-module structures. The section between two adjacent modules' centre seen as element. Based the above assumption, six-degree-of-freedom motion module's both affected by hydrodynamic interaction with its module restricted deformation condition...
The flow past a cylinder in proximity to plane wall is investigated numerically for small gap ratios. Three vortex dynamic processes associated with different hairpin generation mechanisms are identified the first time, and wake-induced turbulent transition analysed. shedding suppressed at $G/D = 0.1$ , while spanwise generated via Kelvin–Helmholtz instability evolves into vortices. For $G/D= 0.3$ upper lower rollers alternatively from cylinder, interact secondary vortex. split merges roller...
A frequency capture phenomenon in which the dominant response of downstream cylinder is same as that upstream despite differences their physical characteristics was recently experimentally identified. The mechanism this investigated by flow around two cylinders with unequal diameters undergoing flow-induced vibrations (FIV) using open-source code OpenFOAM. Two FIV systems, a large stationary/vibrating and vibrating cylinder, are used for simulation. free to vibrate both in-line cross-flow...
