Comparative study of experimental and numerical analysis of fluid parameter around tall buildings

Abstract

The rapid growth of the urban population and the consequent pressure of limited space have influenced city residential developments, which ultimately resulted in the sudden sprouting of tall and vertical structures. The structural system of present day has become less stiff and lighter than earlier, hence are usually more sensitive to the effect of lateral loads acting on it, especially wind loads. Inorder to ensure serviceability of the structure, the analysis and design must be carried out efficiently. From being termed a simple static drag force, wind force gained new dimension taking into consideration the dynamic aspects, thus demanding more attention in structural analysis and design. This paper deals with the comparative study of fluid parameters around tall structures when subjected to the traditional experimental analysis by Wind Tunnel test and the most modern approach of numerical simulation using Computational Fluid Dynamics (CFD). The comparison of result obtained via both of the above-mentioned approach and the further extend of possibilities in adopting CFD is also discussed.
