The Vortex lattice method, (VLM), is a numerical method used in computational fluid dynamics, mainly in the early stages of aircraft design and in aerodynamic education at university level. The VLM models the lifting surfaces, such as a wing , of an aircraft as an infinitely thin sheet of discrete vortices to compute lift and induced drag .
A large air vortex cannon, with a 9 feet (2.7 m) wide barrel and a displacement volume of 2,873 US gallons (10.88 m 3) was built in March 2008 at the University of Minnesota, and could blow out candles at 180 feet (55 m). [6] [7] In 2012, a large air vortex cannon was built for Czech Television program Zázraky přírody (lit. ' Wonders of ...
Winglets increase the effective aspect ratio of the wing, changing the pattern and magnitude of the vorticity in the vortex pattern. A reduction is achieved in the kinetic energy in the circular air flow, which reduces the amount of fuel expended to perform work upon the spinning air [citation needed].
Four basic configurations which have used vortex lift are, in chronological order, the 60-degree delta wing; the ogive delta wing with its sharply-swept leading edge at the root; the moderately-swept wing with a leading-edge extension, which is known as a hybrid wing; and the sharp-edge forebody, or vortex-lift strake.

Vortex generators are most often used to delay flow separation.To accomplish this they are often placed on the external surfaces of vehicles [4] and wind turbine blades. On both aircraft and wind turbine blades they are usually installed quite close to the leading edge of the aerofoil in order to maintain steady airflow over the control surfaces at the trailing edge.

Sleep is a normal physiological process, but it sometimes requires work to make it truly restorative, notes Dr. Haq. Pay attention to your body, exercise regularly, eat healthy foods and see your ...
Vortex Studio is a simulation software platform developed by CM Labs Simulations. It features a real-time physics engine that simulates rigid body dynamics , collision detection , contact determination, and dynamic reactions.
The remarks come over a week after California Gov. Gavin Newsom invited Trump to visit the state and meet the victims impacted by the wildfires.
