|Title:||A Numerical Study of the Effect of Wind Barriers on Traffic and the Bridge Deck||Authors:||Keenahan, Jennifer; Zhang, Yuxiang; Cardiff, Philip||Permanent link:||http://hdl.handle.net/10197/11617||Date:||28-Aug-2020||Online since:||2020-10-06T14:08:34Z||Abstract:||Wind actions can have a great impact on both bridges and traffic on bridges. However, structures designed to shelter the traffic from wind can influence the aerodynamic performance of the bridge deck, especially for long-span bridges. This study compares the effect of non-perforated walls and perforated walls used as wind barriers for traffic by conducting Computational Fluid Dynamics (CFD) simulations on three-dimensional geometries of a four-lane bridge deck. Steady-state simulations employ the Reynolds-Averaged Navier Stokes (RANS) method with the k-epsilon turbulence model and all simulations use parallel computing. An open-sourced software OpenFOAM is used.||Funding Details:||University College Dublin||Type of material:||Conference Publication||Keywords:||Wind; Bridges; CFD modelling||Other versions:||http://www.cerai.net/||Language:||en||Status of Item:||Peer reviewed||Conference Details:||The Civil Engineering Research Association of Ireland, Cork, Ireland, 27-28 August 2020|
