Computational wind engineering using finite element package ADINA
… tall and long span structures is governed by the wind forces. Inadequate research in the field of wind dynamics has forced engineers to rely on design codes or wind tunnel tests for sufficient data. The present work uses a computational wind dynamics method to compare the coefficient of pressure …

CFD modelling of flow distortion using OpenFOAM
… fluid dynamic (CFD) study of flow related to wind engineering. The open source CFD code OpenFOAM was applied to three cases (i) flow over an oil platform, (ii) flow over a complex terrain and (iii) flow over a met mast. In order to verify the results, experimental work was undertaken using a …

Wind tunnel investigation of wind load on a ground mounted photovoltaic tracker
Wind loading is an important environmental factor to be considered in design of components and support structures of ground mounted photovoltaic tracker systems (PVT). Current understanding of action of wind on such systems is incomplete. Over the past decade, a number of investigations devoted to …

Wind-induced dynamic response of bridges
Wind loading has long played a significant role in bridge design. Some spectacular failures, such as the Tay Bridge (Scotland, 1879), or the Tacoma Narrows Bridge (Washington State, 1940) acted as a painful reminder to engineers in case they had forgotten the importance of wind loading. Today, a …

Wind flow characteristics and their effects on low-rise buildings
… turbulence and other properties of the incident wind in loading effects. Much of the debate on wind-tunnel simulation priority in the wind engineering community has failed to distinguish the different effects the incident wind has on two types of quantities: single events, e.g., minimum (peak) …

Experimental and computational determination of wind loads on netted/sheeted scaffolds.
This thesis describes an investigation into the wind loading on access scaffolds erected around a cubical building, clad by impermeable sheeting or permeable debris netting. The subject was investigated experimentally by tests in a wind-tunnel and theoretically using computational fluid dynamics …

Numerical evaluation of wind effects on buildings
The wind environment around buildings and the wind pressures on building surfaces are studied by scale-model experiments in wind tunnels and confirmed by full scale measurements. Such experiments are often expensive and time consuming. Computational wind engineering as a new branch of computational …

Analysis of Bridge Deck Sections by Pseudo-compressibility method based on FDM and LES: Improving Performance through Implementation of Parallel Computing
<p>The incidence of wind on bridges produces static and dynamic loading that must be adequately addressed when designing bridges. Dynamic loading is the primary concern, as the amplitude of the structures response to the applied loading may be greatly amplified. Ideally, the bridge's properties …
