Combined Simultaneous Flow Visualization/Hot-Wire Anemometry for the Study of Turbulent FlowsSource: Journal of Fluids Engineering:;1980:;volume( 102 ):;issue: 002::page 174Author:R. E. Falco

Abstract: The measurement of coherent motions in turbulent and unsteady flows is discussed. A technique which discriminates these motions based upon the patterns they create by scattering light from a fog of tiny oil drops is described. It is shown that hot-wire anemometry can be used in this oil fog so that hot-wire data can be conditionally sampled to the visual patterns, giving directly interpretable measures of the importance of the selected features. The three-dimensionality of the coherent motions can also be directly accounted for, using mutually orthogonal sheets of light. Results of step flows, and zero and favorable pressure gradient flows are described.
