Experimental investigation of Vortex-Induced Vibration on rigid, smooth and inclined cylinders
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2009)
This paper presents new experimental results of Vortex-Induced Vibration (VIV) on inclined cylinders. Models are mounted on a low damping air-bearing elastic base with one degree-of-freedom, constrained to oscillate only ...
Experimental investigation of flow-induced vibration on isolated and tandem circular cylinders fitted with strakes
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2010)
The effect of varying the geometric parameters of helical strakes on vortex-induced vibration (VIV) is investigated in this paper. The degree of oscillation attenuation or even suppression is analysed for isolated circular ...
Unsteady thermoelastic analysis of a circular disk with a hot central core and subjected to adiabatic conditions
(Elsevier, 2000-04)
The unsteady thermoelastic analysis of a cooling circular disk or cylinder which is originally at uniform temperature is a classical problem of the theory of thermal stresses. More recent studies consider the case of ...
Secondary instabilities in the flow around two circular cylinders in tandem
(CAMBRIDGE UNIV PRESS, 2010)
Direct stability analysis and numerical simulations have been employed to identify and characterize secondary instabilities in the wake of the flow around two identical circular cylinders in tandem arrangements. The ...
Circular Cylinder Drag Reduction By Three-Electrode Plasma Symmetric Forcing
(American Society of Mechanical Engineers, 2017-06)
This study reports an efficient reduction of the drag exerted by a flow on a cylinder when the former is forced with a plasma actuator. A three-electrode plasma device (TED) disposed on the surface of the body is considered, ...
Floquet stability analysis of the flow around an oscillating cylinder
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2009)
This investigative work is concerned with the flow around a circular cylinder submitted to forced transverse oscillations. The goal is to investigate how the transition to turbulence is initiated in the wake for cases with ...
Numerical experiments of the flow around a bluff body with and without roughness model near a moving wall
(2020-03-01)
Numerical tests at high Reynolds number flows were taken on circular cylinder placed near and parallel to a moving ground. A moving ground running at the same speed as the free stream eliminates the confusing effects of ...
Computational simulation of the flow-induced vibration of a circular cylinder subjected to wake interference
(London, 2013)
In this work, we considered the flow around two circular cylinders of equal diameter placed in tandem with respect to the incident uniform flow. The upstream cylinder was fixed and the downstream cylinder was completely ...
Vortex induced vibrations suppression for a cylinder with plasma actuators
(Academic Press Ltd - Elsevier Science Ltd, 2020-03)
We propose the use of plasma actuators in order to control the vortex induced vibration phenomena (VIV) originated by an airflow around a rigid circular cylinder. The body was placed in a closed loop wind tunnel and mounted ...
