Abstract

Skin friction and velocity measurements were measured in zero and adverse pressure gradient boundary layers using oil-film interferometry and single hot-wire sensors. Oil-film interferograms were analyzed using the Empirical Mode Decomposition (EMD) and Hilbert transform techniques [9] that, in contrast to commonly used Fourier based techniques, are less subjective and superior for treating amplitude and frequency modulated data [4]. As an independent technique, the oil-film measurement has been used to assess the use of the Clauser-chart [5]. For strong pressure gradients, at the Reynolds numbers considered here, the Clauser-chart results were found to underestimate the wall-shear stress velocity as found by oil-film interferometry.
