Voorbeelden van vane

• The helical vortex precesses about the tube centreline in the same direction as the rotation imparted by the swirl vanes.

• Examples include heart valve leaflets, parachute canopies, thin airfoils (including bird, insect, or bat wings), sails, kites, flags, and weather vanes.

• The vortex centre and free stagnation point were found using the vane probe.

• This effect would be minimized if the vanes are made perfectly symmetric.

• A turbo molecular pump, backed by a rotary vane pump is connected to the chamber.

• Nevertheless, it is important to remember here that the vane was of k i t e size; a 1.0 cm square.

• This is a very thin vane, normally 1 x 1cm, mounted on a spindle so that the vane can rotate.

• If this idea was completely correct the vane would have reversed its direction of rotation as it was moved into the core.

• Both a turbine airflow meter indicating to 0.1 m/s and a sensitive wind vane did not respond to airflow in the experimental area.

• Discharge was controlled independently of the swirl vanes with a motoroperated cone valve at the upstream end of the stilling chamber.

• The inertial oscillations, though unsteady, may produce a non-linear higher order steady component by interacting with the vanes in the tank.

• Vane directions agreed everywhere with the calculated streamline directions, within the ability of the eye to judge.

• These conditioning units included diffusers, corner vanes, a honeycomb, screens and a contraction and were inserted within the channel to suppress any spatial and temporal nonuniformity of the flow.

• This is illustrated by the weather vane.

• Vane was himself surprised that there had not been more escapes and, therefore, damage.
