Computational modeling of wind flow and its effect on a cubical building using Large Eddy Simulation (LES) technique
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 7
Abstract
The wind flow and its effects over cubical buildings lying in close vicinity in urban areas generates flow interference effects causing problems related to pollution, pedestrian comfort and ventilation within the buildings thus promoting a lot of research interest in this area during the last few years. The wake and its characteristics of a building has drawn attention for various applications like dispersion of pollutants downwind of conventional or nuclear power plants, airport runway interference effect, take-off/landing limitation at heliports, pedestrian wind comfort, and wind loads on structures.Computational Fluid dynamics (CFD) is one of the promising technologies for investigating these important issues, which will not necessarily be solved by traditional wind tunnel technology. Large Eddy Simulation Technique (LES) shall be used to predict the flow physics- external flow around the building. The proposed work has been accomplished through numerical simulation using ANSYS-FLUENT 12.1 solver.The effects have been quantified in terms of the pressure distribution, turbulence in and around the building, threedimensionality effect on the overall flow patterns
