Dynamics of vortex shedding from slender cones [PDF]
PhDThe dynamics of vortex shedding from bluff bodies has been investigated experimentally for many decades, with the simple geometric case for the investigation being a uniform circular cylinder aligned with its axis normal to the flow. Even though

Investigating the effect of rotational degree of freedom on a circular cylinder at low reynolds number in cross flow [PDF]
Numerical simulations of Vortex-Induced Vibrations (VIV) of a circular cylinder in cross flow with a rotational degree of freedom about its axis have been carried out by means of a finite-volume method.

Investigation of Fractal Characteristics of Karman Vortex for NACA0009 Hydrofoil
A Karman vortex is a phenomenon of fluid flow that can cause fluctuation and vibration. As a result, it leads to fatigue damage to structures and induces safety accidents.

Application of lattice constructions for protection of high-rise chimneys from vortex shedding [PDF]
Consideration of vortex shedding response is important for high-rise chimneys when air flow causes strong vibrations of the structure in a certain range of wind speeds when the frequency of natural vibrations of the structure coincides with the frequency

Numerical Assessment of Flow Energy Harvesting Potential in a Micro-Channel
A micro-energy harvesting device proposed in the literature was numerically studied. It consists of two bluff bodies in a micro-channel and a flexible diaphragm at its upper wall.

Cylindrical structures are widely used in offshore and marine engineering, but they may suffer from vortex-induced vibration under the influence of ocean or wave currents, which can lead to severe fatigue damage. In this study, we applied the open-source

Investigation into the Strouhal numbers associated with vortex shedding from parallel-plate thermoacoustic stacks in oscillatory flow conditions [PDF]
This paper investigates vortex shedding processes occurring at the end of a stack of parallel plates, due to an oscillating flow induced by an acoustic standing wave.

Prediction method of hydrofoil vortex shedding frequency at high Reynolds numbers
[Objectives] Flow around hydrofoils under high Reynolds number is always a hot topic in hydrodynamic field due to its complicated principle and difficult calculation. The Discrete Vortex Model (DVM) based on vorticity and stream function formulation is a

Vortex shedding in a model of superflow [PDF]
The present article represents part of the PhD. dissertation by C. Josserand. We discuss the nucleation of quantized vortices in the nonlinear Schrödinger equation (NLS) for a flow around a disk in two spatial dimensions. It appears that the vortices are nucleated when the flow becomes locally (at the edge of the disk) supersonic.
