Performance Comparison of Different Building Shapes using Wind Tunnel and Computational Model

An increasingly common way of assessing renewable energy is the building integrated wind turbine (BIWT). Wind velocity (V) is a critical parameter when it comes to determining potential energy from wind turbines (P). Along with being affected by the height, the shape of the building can also increase wind velocity. CFD simulations taken from previous research have revealed that round shape building increases velocity up to 30%. This study focuses on the wind response of square and top-rounded-shaped building models, and its optimization based on variations in the wind velocity. To observe an accurate airflow pattern and wind speed on the top of a building, a five-step analysis framework is presented here. Wind tunnel experiments and computer simulations were conducted here. The boundary layer wind tunnel has tested rigid models of three buildings of 1:150 scale in detail. The results show that, to install wind turbines on rectangular roofs with flat surfaces, the streamline should be followed. With this method, wind velocity can be increased significantly compared to a higher turbine. Additionally, round corners can produce wind velocity of up to 34% respectively greater than sharp corners beside a building.
