WebBLLs are categorized as open-loop or closed-loop systems. An open-loop BLL entails a disconnected inflow and outflow, which is energetically inefficient. In contrast, closed-loop BLLs conserve energy by recirculating airflow. WebSince you are building an open-circuit wind tunnel, you don't need to study anything that these resources say about closed-circuit wind tunnels. Important Notes Before You Begin This design is for an open-circuit, …
