| Abstract: | In order to clarify the mechanisms of wind waves, the air and water flows close to the water surface were simultaneously measured by using the Image Velocimetry, the IV. In this study, a Particle Tracking Velocimetry, so-called PTV, was used as IV, which can measure the velocity vectors in the vicinity of the water surface. The experiments were carried out in the range where whitecaps cannot appear. From the measured planar velocity distributions, the instantaneous vorticity distributions in air and water were evaluated. | |
