Wind Directional Effect on a Single Storey House Using Educational Wind Tunnel

Abstract

Wind tunnel testing of single-storey isolated building with 1: 100 scale down model was carried out in an open circuit wind tunnel without roughness elements facilities. The gable roof building model with 30˚ roof pitch was studied for wind directions of 0˚, 30˚, 45˚, 60˚ and 90˚. Pressure measurements were performed on all the walls and the roof (Zone 1, 2, 3, 4 and 5) of the building model with wind speed of 12 m/s. The results showed that the high suctions were generally induced by the 90˚ wind direction for Zone 1 and 60˚ and 90˚ wind directions for Zone 2. Mostly, high suction was also observed in case of 45˚ and 60˚ wind direction in Zone 3. In zone 4 and zone 5, high suction was generally induced by the 0˚ wind direction.
