3D CFD Simulation of Vortex-induced Vibration of Cylinder
(INT SOC OFFSHORE POLAR ENGINEERS, 2011)
The 3D flow around a circular cylinder free to oscillate transversely to the free stream was simulated using Computational Fluid Dynamics (CFD) and the Spalart-Allmaras Detached Eddy Simulation (DES) turbulence model for ...
Numerical framework for stress cycle assessment of cables under vortex shedding excitations
(Techno Press, 2019)
Copyright © 2019 Techno-Press, Ltd.In this paper a novel and efficient computational framework to estimate the stress range versus number of cycles curves experienced by a cable due to external excitations (e.g., seismic ...
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 ...
Passive scalar transport mediated by laminar vortex rings
(Institute of Physics Publishing, 2017)
Numerical simulations were used to study the dynamics of a passive conservedscalar quantity entrained by a self-propelling viscous vortex ring. The trans-port and mixing process of the passive scalar variable were studied ...
Control and suppression of vortex shedding from a slightly rough circular cylinder by a discrete vortex method
(2020-09-01)
A discrete vortex method is implemented with a hybrid control technique of vortex shedding to solve the problem of the two-dimensional flow past a slightly rough circular cylinder in the vicinity of a moving wall. In the ...
Study of surface roughness effect on a bluff body — The formation of asymmetric separation bubbles
(2020-11-01)
Turbulent flows around bluff bodies are present in a large number of aeronautical, civil, mechanical, naval and oceanic engineering problems and still need comprehension. This paper provides a detailed investigation of ...
Development of a new Lagrangian vortex method for evaluating effects of surfaces roughness
(2019-03-01)
The main contribution of this paper is to develop a new methodology to include effects of surface roughness on aerodynamic of bodies. The numerical approach simulates the mechanism of vortex shedding of a rough circular ...
