Abstract

This thesis focuses on investigation and discussion of the characteristics of fluid flow around bluff bodies in which the simulations are done using Computational Fluid Dynamic and experimentally in subsonic wind tunnel. Various models have been tested to developed understanding and proper modeling techniques for the flow around such bodies. Throughout this thesis, the Large Eddy Simulation has been validated through comparative study with experiment work. This research section concentrates on modeling flow characteristics around bluff bodies to investigate the impact of fluid flow on them. This aids in the understanding of a more complex flow in engineering applications. The major part of the work discusses on the drag force of flow around simple circular cylinder and flat plate. From the analysis, the results state that the high velocities produced large drag forces. Both of CFD computations and experiments have been performed in the different range of Reynolds numbers between 50000 to 200000 that tested at the different shape of the bodies. Finally, the conclusions outline the achievements and findings of the work done in this thesis and give recommendations for further research on the topic.
