Boundary-Layer Characterization on Moving Walls by an Embedded Laser Velocimetry Technique

An embedded laser velocimetry measurement (ELV) method, suited for unsteady boundary-layer measurements on oscillating airfoils of arbitrary shape, has been developed. This method, based on an ELV optical fiber option, is an extension of a previous one tested on one-dimensional longitudinal velocity field measured over an oscillating flat-plate model.
