21Flow separation — All solid objects travelling through a fluid (or alternatively a stationary object exposed to a moving fluid) acquire a boundary layer of fluid around them where viscous forces occur in the layer of fluid close to the solid surface. Boundary… …
22vortex ring state — The operating state of a helicopter main rotor in which the axial flow through the rotor is opposite to the axial flow outside the rotor disc area and to the rotor thrust. It is an unstable condition of powered flight in which the helicopter… …
23vortex generator — Small, low aspect ratio airfoils mounted in pairs on the upper surface of the wings of high speed aircraft. These project into the boundary layer and are meant to energize the stagnant boundary layer to promote better flow over the surface and… …
24Secondary 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 …
25Taylor-Couette flow — The Taylor Couette flow consists of a viscous fluid confined in the gap between two rotating cylinders. For low angular velocities, measured by the Reynolds number Re, the flow is steady and purely azimuthal. This laminar basic state is known as… …
26steady streamlined flow — An airflow whose parameters (e.g., speed, direction, pressure, etc.) are constant at any point with respect to time. The airflow could be linear, a controlled separated flow, a leading edge vortex flow, or a vortex trail. Vortex streamline flow.… …
27Taylor vortex — Taylor vortices (after G. I. Taylor) are vortices formed in rotating Taylor Couette flow when the Taylor number (mathrm{Ta}) of the flow exceeds a critical value mathrm{Ta c}. For flow in which :mathrm{Ta}mathrm{Ta c} …
28rotary flow — The movement of the oil as it is carried around by the pump and turbine in a torque converter. The rotary motion is not caused by the oil passing through the pump, to turbine, to stator, etc., as is the case with vortex flow. Rotary flow is at… …
