Contributions Towards a Large Eddy Simulation Best Practice Guide for the Numerical Prediction of Wind Loads on Tall Buildings
The influence of the domain height and width, and mesh and time step size on the results of a LES (Large-Eddy Simulation) to estimate wind loads on tall buildings was investigated. The results shall contribute to a future LES BPG (Best Practice Guide). Therefore, the wind flow around the CAARC Standard Tall Building, a well-established benchmark, was simulated with the software package Star-CCM+. The CDRFG (Consistent Discrete Random Flow Gener- ation Technique) was used to generate a turbulent inflow. The obtained results showed a good agreement with measurements from the BLWT (Boundary Layer Wind Tunnel) at the University of Western Ontario, Canada. Thus, the results indicated that the well-known rec- ommendations regarding the height and width of the computational domain could be reduced for LES. Moreover, potential fields for further research in the field of wind load estimation with LES were detected. For example, the choice of the most suitable selection of mesh sizes throughout the domain to obtain reasonable results and maintain an acceptable running time of the simulation.
