Calculation of wind induced loads is essential for design of tall structures. With the advancements in computer technologies, CFD simulations are now a good alternative for wind tunnel tests for knowing the wind induced responses of a structure. In current scenario, presence of nearby structures exhibit Interference effects. In this paper, CFD simulation is carried out for a particular arrangement of group of tall buildings. Pressure coefficients on the same have been studied using Computational Fluid Dynamics (CFD) technique. Buildings of different heights are taken into consideration. The effect of different wind incidence angles on the pressure coefficients on all the faces of Principal Building has been investigated. Also, the pressure coefficient contours on all the faces of all buildings for wind incidence angles of 0°, 30°, 60° and 90° are plotted. ANSYS CFX is used for carrying out the CFD simulation.
