free vortex flow
1free-vortex compressor — An axial flow compressor designed to impart to the fluid tangential velocities that are inversely proportional to the distance from the axis of rotation, such as in a vortex …
2Vortex — A vortex (pl. vortices ) is a spinning, often turbulent, flow of fluid. Any spiral motion with closed streamlines is vortex flow. The motion of the fluid swirling rapidly around a center is called a vortex. The speed and rate of rotation of the… …
3Free surface — In physics a free surface is the surface of a body that is subject to neither perpendicular normal stress nor parallel shear stress,cite web |url=http://www.vishay.com/company/brands/measurements group/guide/glossary/freesurf.htm |title=Glossary …
4Vortex ring — A vortex ring, also called a toroidal vortex, is a region of rotating fluid moving through the same or different fluid where the flow pattern takes on a doughnut shape. The movement of the fluid is about the poloidal or circular axis of the… …
5Vortex Indicator — The Vortex Indicator is a technical indicator invented by Etienne Botes and Douglas Siepman to identify the start of a new trend or the continuation of an existing trend within financial markets. It was published in the January 2010 edition of… …
6Vortex engine — The concept of a Vortex Engine, independently proposed by Norman Louat [Louat s International Patent Application is PCT/AU99/00037] and Louis Michaud [Michaud s U.S. Patent is US 2004/0112055 A1, Atmospheric Vortex Engine ] , aims to replace… …

8Secondary flow — In fluid dynamics, a secondary flow is a relatively minor flow superimposed on the primary flow, where the primary flow usually matches very closely the flow pattern predicted using simple analytical techniques and assuming the fluid is inviscid …
9Rankine vortex — The Rankine vortex model is an attempt to describe the velocity profile through vortices in real, viscous, fluids. It is named after its creator, William John Macquorn Rankine.A swirling flow in a viscous fluid is characterized by a forced vortex …
10Potential flow — streamlines around a NACA 0012 airfoil at 11° angle of attack, with upper and lower streamtubes identified. In fluid dynamics, potential flow describes the velocity field as the gradient of a scalar function: the velocity potential. As a result,… …
