Control of suction distributions on Boundary layer suction systems for automotive wind tunnels

Wind tunnels are used to study airflows around objects like cars, airplanes and ice-skaters. This is done, simulating the real world, by blowing an airflow over a fixed body. In the real situation an object moves through the air, while in a wind tunnel it is the air that is moving. So a wind tunnel needs to generate an airflow. In this airflow,...

Boundary layer suction configurations with minimal pump requirements for multi-element airfoils

High lift systems are indispensable but complex and heavy systems so new methods to allow lighter and simpler high lift systems are actively sought after. One of the methods that have already proven to be able to increase high lift performance is boundary layer suction. In practice however the application of it is uncommon mainly due to the...
