Bridge deck flutter derivatives: Efficient numerical evaluation exploiting their interdependence
(Elsevier, 2015-01)
Increasing the efficiency in the process to numerically compute the flutter derivatives of bridge deck sections is desirable to advance the application of CFD based aerodynamic design in industrial projects. In this article, ...
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 ...
An Open-Source Framework for Aircraft Damage Simulation in Engine Failure Events
(Elsevier, 2022)
[Abstract] The aerospace industry demands designs capable of withstanding the simultaneous collapse of several structural elements. Examples of this failure scenario are propeller blade or uncontained engine rotor failures, ...
Reliability index based strategy for the probability-damage approach in fail-safe design optimization (β-PDFSO)
(Springer Nature, 2023)
[Abstract:] This research proposes a new formulation for fail-safe size optimization, considering the probability of occurrence of each failure scenario and the random structural parameters as sources of uncertainty. ...
Multi-bubble scheme and structural analysis of a hypersonic stratospheric flight vehicle
(Elsevier, 2022)
[Abstract:] The STRATOFLY MR3 vehicle is the main objective of the STRATOFLY project, which aims to develop a hypersonic air breathing concept capable of covering antipodal routes in less than three hours. The aircraft ...
Square Cylinder Under Different Turbulent Intensity Conditions by Means of Small-Scale Turbulence
(WIT Press, 2021)
[Abstract] The phenomenon of turbulence is present in almost every type of flow in practical applications. Depending on its level of intensity and length scale, it can modify both the aerodynamic and aeroelastic performance ...
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 ...
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 simplified CFD approach for bluff-body aerodynamics under small scale free stream turbulent flow
(Elsevier, 2023)
[Abstract:] The study of free stream turbulence (FST) effects on bluff bodies by means of computational approaches has been addressed so far mainly applying scale resolving methods adopting a three-dimensional domain, which ...
