Buildings significantly affect the wind flow pattern over an urban area, leading to regions with an accelerated wind flow. The change in wind flow influences pollutant dispersion, urban microclimate, formation of fog and haze, urban heat island, comfort of pedestrians, and wind-created noise. It is important to include the simulation of wind flow around buildings in the early architectural design stage. The paper investigates the effect of different shapes of buildings on the wind flow pattern using Computational Fluid Dynamics (CFD) simulation. Results have been represented through pressure, velocity, and turbulence kinetic energy contours for five different cases. The ANSYS software was employed to solve the flow governing equations. The standard k-s turbulent model was used for turbulence modeling while the SemiImplicit Method for Pressure Linked Equation (SIMPLE) algorithm was applied as a solver for governing equations. This study clearly illustrates that different building shapes generate different wind flow patterns.
