124Controlled aerodynamic instability phenomena — The term controlled aerodynamic instability phenomena was first used by Cristiano Augusto Trein[1] in the Nineteenth KKCNN Symposium on Civil Engineering [2] held in Kyoto – Japan in 2006. The concept is based on the idea that aerodynamic… …
125Baroclinity — In fluid dynamics, the baroclinity (sometimes called baroclinicity) is a measure of the stratification in a fluid. A baroclinic atmosphere is one for which the density depends on both the temperature and the pressure; contrast this with… …
126Scalar potential — A scalar potential is a fundamental concept in vector analysis and physics (the adjective scalar is frequently omitted if there is no danger of confusion with vector potential). Given a vector field F, its scalar potential V is a scalar field… …
127Helmholtz's theorems — In fluid mechanics, Helmholtz s theorems describe the three dimensional motion of fluid in the vicinity of vortex filaments. These theorems apply to inviscid flows and flows where the influence of viscous forces is small and can be… …
128Helicopter noise reduction — is a topic of research into designing helicopters which can be operated more quietly, reducing the public relations problems with night flying or expanding an airport. In addition, it is useful for military applications in which stealth is… …
