3D LES simulations of a static and vertically free-to-oscillate 4:1 rectangular cylinder: effects of the grid resolution
(Elsevier, 2019)[Abstract:] In the present study, the aerodynamics of the flow fields around a static and vertically free-to-oscillate 4:1 rectangular cylinder are analysed by means of 3D LES simulations, adopting the OneEqEddy viscosity ... -
A Computational Study on the Aerodynamics of a Twin-Box Bridge With a Focus on the Spanwise Features
(Elsevier, 2021)[Abstract] The wind flow around twin-box decks is particularly complex due to the very important role played by the slot distance between girders and the presence of the downwind box that is immersed in the wake of the ... -
Aerodynamic performance of twin-box decks: a parametric study on gap width effects based on validated 2D URANS simulations
(Elsevier, 2018)[Abstract:] 2D URANS simulations are conducted aiming to study the aerodynamic performance under smooth flow of twin-box decks depending on the gap distance between girders. The Stonecutters Bridge is taken as the reference ... -
Semi-automated setup of CFD simulations of rectangular cylinders and streamlined box decks
(WIT Press, 2020)[Abstract:] A piece of software that acts as a Graphical User Interface (GUI) for the setup of computational fluid dynamics (CFD) models that are solved by means of the open source code OpenFOAM, is presented. The software ... -
Study of a static and vertically free-to-oscillate 4:1 rectangular cylinder by means of 2D URANS simulations
(WIT Press, 2018)[Abstract:] Flexible structures, such as cable-supported bridges, are prone to suffer from vortex-induced vibrations (VIV) under wind flow, as their span lengths are steadily growing in the last decades. VIV is a phenomenon ... -
Verification Approaches for the 3D Static LES Simulations of the Stonecutters Bridge Deck
(WIT Press, 2021)[Abstract] In computational fluid dynamics (CFD) simulations, verification is the process of identifying both the spatial and the temporal discretisations providing relatively insensitive model results. The underlying goal ... -
Wind tunnel study on the effect of the gap width in the aerodynamic and aeroelastic responses of twin-box decks
(WIT Press, 2018)[Abstract:] Twin-box decks have recently been introduced in long-span bridges because this type of slotted cross-section provides flutter critical wind speeds higher than mono-box streamlined decks for flexible structures. ...
