Influence of wind barrier configuration on driving space over bridge decks: A PIV-based parametric study [PDF]

Scientific Reports
Wind-induced vibrations, such as vortex-induced vibrations, occur on long-span bridges because of their flexibility, especially for bridges with centrally slotted box girders, which may severely affect structural safety and driving comfort.

Review of OpenFOAM applications in the computational wind engineering: from wind environment to wind structural engineering

Meccanica
Abstract The use of computational fluid dynamics (CFD) in the wind engineering (WE) is generally defined as computational wind engineering (CWE). Since its foundation in 2004, the use of OpenFOAM in CWE has been increasing progressively and covers nowadays a wide range of topics, from wind environment to wind structural engineering.
