Analysis of wall shear stress probes in large amplitude unsteady flows - 281-290 p.

The measurement of the mass transfer rate to flush mounted wall electrodes is a commonly used method to determine the wall shear stress. An analysis for the performance of these probes in the presence of large amplitude unsteady flows is presented. This is accomplished by using numerical solutions of the direct (the variation of the wall shear stress with time is given) and the inverse problem (the variation of mass transfer rate with time is given). For cases in which flow reversal occurs additional information about the flow direction is needed.
