Abstract
With the advancements in construction technologies, conventional shaped buildings have paved the way for the construction of buildings with unconventional designs that meet the aesthetic demands of modern times as well as counter the effects of wind more effectively. These aerodynamic modifications could be embedded in the basic structural design of the building, or these could be implemented by bringing about minor changes in the exterior of the conventional building. In this paper, numerical investigation is conducted on a square and 180° twisted square (helical) building model based on the wind tunnel experiment study. ANSYS FLUENT software is used for numerical simulation. Velocity profile inside wind tunnel and mean pressure coefficient on the faces of helical building for 0° wind direction is numerically validated with experimental result. Further, wind force coefficients evaluated on different faces of helical and square building are compared with each other under wind incidence angle of 0, 15, 30 and 45°. It was observed that the magnitude of force coefficient decreases for helical building when compared with square building.
