More Information
Summary:The invention relates to a method for testing a water surface fine-speed flow field. A light source is used for illuminating tracer particles, and with the cooperation of a CCD aperture, a V-shaped convergence and divergence flow field formed by tracer particles transmitted to the water surface by internal waves excited by a dragging model is photographed. The measurement of flow field speed is realized by following the speed of the tracer particles which move together with the flow field by using the above principle. The method is simple and effective, is high in application flexibility, and realizes non-contact and non-interference 'surface type' measurement of an mm/s order water surface flow field.
