Strouhal Number Measurement for Novel Biomimetic Folding Fins Using an Image Processing Method

The aim of the paper is to present parameters new biomimetic folding fins measured using image processing. Tests were carried out for different types and compared most popular on market. A noninvasive processing method was used estimate divers’ velocities in vertical horizontal directions frequency amplitude fin trailing edge, as a result, Strouhal number calculated. These tests are continuation studies conducted water tunnel, where efficiency ratio generated thrust electrical energy consumption, taking into account mechanical leg manipulator well velocity. helped us analyse fin–diver–water system properties fins, particular newly designed fins.
