0 a closed passage or room through which currents of air are forced in order to study the effects of moving air on aircraft and other vehicles --
The acoustic waves were produced by a loudspeaker placed outside the wind tunnel and guided through a tube into the tip of the chamber.
Not only the mean velocity and pressure gradients in the wind tunnel, but the tunnel turbulence level, as well, must be minimized.
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.
Detailed calculations are given showing the use of such a compressor to heat air for use in a hypersonic 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.
Pebbles from random beach sample used in wind tunnel.
Flow conditions in the wind tunnel were assessed using hot-wire probes, placed just upstream of the splitter-plate trailing edge.
Warhaft measured the fluctuation statistics of the thermal field downstream of one or more parallel heated wires behind a grid in a wind tunnel.
