  Validation experiments of the two-dimensional inverse algorithm are performed
in a pulsed Poiseuille flow exposing shear reversal phases. The method is
applied to the three-segment electrodiffusion (ED) probe for which a specific
nondimensionalization process is suggested, allowing to better link
measurements from a real ED probe to the modeled one in the inverse problem.
This approach provided a two-component wall shear rate in good agreement with
the one obtained from laser Doppler anemometry (LDA) measurements, thus
validating the ability of ED probes to deal with high-amplitude unsteady flows.
The classic linear velocity approximation ($u=sy$) in the probe vicinity is
also investigated in such a flow.
