VORTEX2 was an expanded second VORTEX project, with field phases from 10 May until 13 June 2009 and 1 May until 15 June 2010. VORTEX2's goals were studying why some thunderstorms produce tornadoes while others do not, and learning about tornado structure, in order to make more accurate tornado forecasts and warnings with longer lead time.

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 .

In testing by Boeing and NASA, they reduce drag by as much as 5.5%, compared to 3.5% to 4.5% for conventional winglets. [1] While an increase in span would be more effective than a same-length winglet, its bending moment is greater. A 3 ft (91 cm) winglet gives the performance gain of a 2 ft (61 cm) span increase but has the bending force of a ...
The Strouhal number depends on the Reynolds number, [5] but a value of 0.22 is commonly used. [6] As the unit is dimensionless, any set of units can be used for the variables. Over four orders of magnitude in Reynolds number, from 10 2 to 10 5, the Strouhal number varies only between 0.18 and 0.22. [5]
