Voorbeelden van wind tunnel

• The applied measurement techniques have been used to characterize both plasma generator and plasma flow condition in the plasma wind tunnel.

• Autorotational motion can take place either in free flight or when a plate is pinned to rotate about a given axis in a wind tunnel.

• The single-contraction wind tunnel contained three cells due to small mean flow irregularities.

• Some results of an experimental investigation of forces associated with the subsonic flow of air around a circular cylinder in a wind tunnel are presented.

• This work is mainly an account of some experiments in which drops of water were dropped under gravity into a vertical wind tunnel.

• The hot-wire signals were processed entirely by analogue methods, mainly because wind tunnel time was inexpensive in comparison with available digital computers.

• The particles used in each experiment were placed on the wind tunnel surface, forming a layer roughly 2 cm thick.

• Warhaft measured the fluctuation statistics of the thermal field downstream of one or more parallel heated wires behind a grid in a wind tunnel.

• Flow conditions in the wind tunnel were assessed using hot-wire probes, placed just upstream of the splitter-plate trailing edge.

• Pebbles from random beach sample used in wind tunnel.

• The reason may be that the effects of external heat input or cooling remain confined to a region near the wind tunnel wall.

• Detailed calculations are given showing the use of such a compressor to heat air for use in a hypersonic wind tunnel.

• It was mounted across the width of the wind tunnel 23 m downstream of the test-section entrance with its axis 0.61 m above the floor.

• Not only the mean velocity and pressure gradients in the wind tunnel, but the tunnel turbulence level, as well, must be minimized.

• The acoustic waves were produced by a loudspeaker placed outside the wind tunnel and guided through a tube into the tip of the chamber.
