THREE-DIMENSIONAL FLOWS DEVELOPED UNDER YOUNG WIND WAVES

Abstract

 This study proposed novel technique to measure three-dimensional fluid velocity on a laser sheet at highest resolution, called Stereo Super-Resolution Particle Imaging Velocimetry, which has applied to wind tunnel experiments with aim to identify organizations of three-dimensional flows driven by wind and waves. We observed spanwise flows fluctuating under wind waves that propagated in wind-driven currents. Statistical features of the three-dimensional flows developing with fetch were discussed in this study.
