Abstract

Understanding wind effects on buildings is crucial for mitigating wind-induced damage. This study focuses on the aerodynamic impact of wind on low-rise buildings, with a particular emphasis on vulnerable roof sheathing. Using a k-ε turbulence model, the pressure distribution on a 27° sloped roof is investigated at different free-stream flow velocities. The 27° sloped roof was selected as it represents the average roof pitch commonly found in Southeast Asia, especially in Vietnam. Results are compared using coarse and fine grid configurations around the building. Additionally, Horizontal Axis Wind Turbine (HAWT) with a 1.5m blade diameter is installed 3m above the roof, and its power coefficient is calculated using the actuator disk concept. Comparisons are made between undisturbed flow and flow above the sloped roof. The research findings emphasize the substantial impact of wind speed on the pressure distribution along the sloped roof and the power coefficient of the Horizontal Axis Wind Turbine (HAWT) along the roof surface. This study contributes to a better comprehension of the effects of wind speed on low-rise buildings and provides valuable insights for optimizing HAWT design, especially in the context of sloped roofs.
