Abstract

Intermittency circuits can be used to experimentally determine some of the properties of the turbulent interface that occur in turbulent shear flows. The signal I(x,t) is unity if turbulence is present at x and zero otherwise. Using the signals obtained from detectors at one or more points, certain statistical measures of the interface position Y(x,t) can be determined. Also using a linear array of conventional single hot-wire probes, the position of the interface can be detected continuously to within some small error. The intent of this h-detector is similar to the wave-height detector used in studies of sea surfaces. The signal from the h-detector can be used directly to obtain a variety of important statistical measures of the shape of the interface. Measurements in a plane turbulent wall-jet are shown as an example of the application of an h-detector.
