Illustration of the airflow along an airfoil that exhibits leading-edge stall behavior. Notice the formation of a “short bubble” at a critical point along the leading edge. When the AOA is increased ...
Researchers used the characteristics of owl wings to inform airfoil design and significantly reduce trailing-edge noise. The team used noise calculation and analysis software to conduct a series of ...
A new sound-suppression study provides fresh insight for airfoil design and noise control for micro-aircraft and fluid machinery. The research focused on the concept of trailing-edge noise by using ...
This paper describes a series of ongoing experiments to capture the details of perpendicular vortex-airfoil interaction. Three test cases explored are: 1) a 21% thick symmetric airfoil at 1.1° angle ...
As the angle of attack is increased on a high-performance airfoil, a small amount of separation occurs near the leading edge. This separation causes the boundary layer to transition from laminar to ...
