Study of wind flow pattern around the building with different plan irregularities using computational fluid dynamics


Volume: 1 Issue: 1

Abstract

The motivation behind this study is that of tall structures greater than 45m height is rising in India. Due to the development of such skyscrapers, it results in improper air flow movement in and around the urban environment and hence, finding of actual wind flow pattern is necessary for upcoming construction. For the above study, conducting wind tunnel tests experimentally is too costlier and also time-consuming. To overcome these difficulties, Computational Fluid Dynamics (CFD) plays a useful role in calculating the actual wind flow on the structure. From the results obtained in CFD, the modification can be done in the elevation profile faade features, plan, shape and height of the building such that structure is able to attract minimum wind drag effects. Behavior of air is like a Newtonian fluid and it is important to study fluid-structure interaction. This paper presents an air flow moving around the building for different regular and irregular building plans. Modeling is carried out by using SolidWorks software and wind flow pattern is studied by using Ansys Fluent software. For the present study, different shapes such as a rectangle as regular plan and T-shape, L-shape as irregular plans are chosen. From the results, the flow pattern and wake regions are identified.
