Introduction
Turning vanes, also known as corner vanes or corner fillets, are important components used in wind tunnels to guide airflow smoothly and reduce air resistance at the corners of the plenums [1]. These devices are crucial for accurate testing and research by optimizing airflow control and stability within wind tunnels [1].
Wind tunnels are essential tools for conducting experiments and simulations in industries like aerospace, automotive engineering, and aerodynamics [1]. They provide controlled environments for studying the behavior of objects, such as aircraft models or vehicles, under simulated airflow conditions. However, the corners and edges in wind tunnel plenums can cause turbulence and aerodynamic losses, which can affect the accuracy and reliability of the collected data [1].
To address these issues, turning vanes are strategically placed at the corners of wind tunnel plenums. Their main function is to guide the airflow smoothly around these corners, redirecting it in a controlled manner [1]. By doing so, turning vanes minimize turbulence and reduce air resistance, allowing the air to flow smoothly through the corners. This leads to a more accurate representation of real-world conditions and improves the reliability of experimental results obtained from wind tunnel testing [1].
Turning vanes are designed meticulously to streamline airflow, minimizing disturbances and maximizing the efficiency of the wind tunnel setup [2]. They are usually made from lightweight materials like aluminum or composites to have minimal impact on airflow characteristics [2]. The design and placement of turning vanes require careful consideration of factors such as plenum size and shape, airflow speeds, and desired turbulence levels [2].
