Hot-wire anemometry in hypersonic helium flow [PDF]
Hot-wire anemometry techniques are described that have been developed and used for hypersonic-helium-flow studies. The short run time available dictated certain innovations in applying conventional hot-wire techniques. Some examples are given to show the

The role of freestream turbulence scale in subsonic flow separation [PDF]
The ojective of this work is the clarification of the role of freestream turbulence scale in determining the location of boundary layer separation. An airfoil in subsonic wind tunnel flow is the specific case studied.

Experimental study of two separating turbulent boundary layers [PDF]
A detailed study of two strong adverse pressure gradient flows, one with a free-stream velocity of 35 m/sec, at throat (producing a Re sub theta of 27000 at detachment) and another with free-stream velocity of 22 m/sec, at throat (producing a Re sub ...

Investigations of Effects of Surface Temperature and Single Roughness Elements on Boundary-Layer Transition [PDF]
, 1947 The laminar boundary layer and the position of the transition point are investigated on a heated flat plate. It was found that the Reynolds number of transition decreases as the temperature of the plate is increased.

Dynamic behavior of a beam drag-force anemometer [PDF]
A cantilevered beam with strain gages attached to the fixed ends and the minimax technique were used in an experiment conducted to determine the dynamic behavior of a drag-force anemometer in high frequency, unsteady flow.

Study of the structure of turbulent shear flows at supersonic speeds and high Reynolds number [PDF]
A major effort to improve the accuracies of turbulence measurement techniques is described including the development and testing of constant temperature hot-wire anemometers which automatically compensate for frequency responses.
