NUMERICAL SIMULATION OF FLOW AROUND VARIOUS SHAPE STRUCTURES: A REVIEW

摘要

Structures experience various forces exerted over them inroutine. Thus they are designed in order to bear them all in certainlimits modified with some factor of safety. Wind forces are one of themost important of such forces especially in high rise buildings andtall structures like towers, etc. The wind forces have been tracked inthe vicinity of the structure at the faces treated as walls for the fluidstructure interaction. The study involved comparison of the dragforce magnitude by various angle of attack by wind and the vorticesfor various structural shapes feasible for construction. Theobservation of vortices in the nearby areas and the magnitude offorces has been compared with various other studies and has beenfound in good accordance with each other. This helps in knowing thebuilding shape and construction method to be adopted forconstructing various building shape. CFD is used as a simulationsoftware it predicts drag and lift, pressure distributions etc.
