31Kármán vortex street — A Kármán vortex street is a repeating pattern of swirling vortices caused by the unsteady separation of flow over bluff bodies. They are named after the engineer and fluid dynamicist, Theodore von Kármán [Theodore von Kármán: Aerodynamics]… …
32Helikon vortex separation process — The Helikon vortex separation process is an aerodynamic uranium enrichment process designed around a device called a vortex tube. This method was designed and used in South Africa for producing reactor fuel with a uranium 235 content of around… …
33Mass flow sensor — A mass airflow sensor. A mass air flow sensor is used to find out the mass flowrate of air entering a fuel injected internal combustion engine. The air mass information is necessary for the engine control unit (ECU) to balance and deliver the… …
34Rankine 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 …
35Lamb–Oseen vortex — In fluid dynamics, the Lamb–Oseen vortex models a line vortex that decays due to viscosity. This vortex is named after Horace Lamb and Carl Wilhelm Oseen.[1] The mathematical model for the flow velocity in the circumferential θ–direction in the… …
36Starting vortex — The starting vortex is a vortex which forms in the air adjacent to the trailing edge of an airfoil as it is accelerated from rest in a fluid. [Clancy, L.J., Aerodynamics , Figure 4.7] It leaves the airfoil (which now has an equal but opposite… …
37Potential 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,… …
38Taylor-Green vortex — In fluid dynamics, the Taylor Green vortex is a 2 dimensional, unsteady flow of a decaying vortex, which has the exact closed form solution of incompressible Navier Stokes equations in Cartesian coordinates. It is named after the British… …
39Money Flow Index — (MFI) is an oscillator calculated over an N day period, ranging from 0 to 100, showing money flow on up days as a percentage of the total of up and down days. Money flow in technical analysis is typical price multiplied by volume, a kind of… …
40Karman vortex street — /kärˈmən vörˈteks strēt/ (acoustics) noun The regular vortex pattern behind an obstacle in a flow where vortices are generated and travel away from the object ORIGIN: T von Karman (1881–1963), Hungarian born American engineer …
