In fluid dynamics, vortex shedding is an oscillating flow that takes place when a fluid such as air or water flows past a bluff (as opposed to streamlined) body at certain velocities, depending on the size and shape of the body. In this flow, vortices are created at the back of the body and detach periodically from either side of the body forming a Kármán vortex street. The fluid flow past the object creates alternating low-pressure vortices on the downstream side of the object. The objec… Witryna2 lip 2024 · The complexities of controlling the vortices Optimising the strength and position of the y250 and the cape or J vane vortices is crucial to getting the most out of this part of the car.

"Vortex lift works by capturing vortices generated from the sharply swept leading edge of the wing. The vortex, formed roughly parallel to the leading edge of the wing, is trapped by the airflow and remains fixed to the upper surface of the wing. As the air flows around the leading edge, it flows over the trapped vortex and is pulled in and down to generate the lift. A straight, or moderate sweep, wing may experience, depending on its airfoil section, a leading … " - Image vortices aerodynamics
