Since 1996 a Computational Wind Engineering approach has been developed at the Boundary Layer Wind Tunnel Laboratory (BLWTL). Computational Fluid Dynamics (CFD) simulations are performed using state of the art commercial codes, such as FLUENT, and/or in house developed, Large Eddy Simulation codes. The aim of the Computational Wind Engineering direction at the BLWTL is to complement the well-established experimental capabilities of the Laboratory for studies such as:
