Abstract

Hull slamming constitutes an important class of impulsive loading for marine composites. In this work, we experimentally assess the effectiveness of particle image velocimetry (PIV) to resolve the flow physics and infer the pressure distribution in water entry problems. Toward this aim, PIV experiments are performed on a rigid wedge with a deadrise angle of 37° symmetrically impacting the water surface by free falling from a height of 50 cm. PIV measurements are systematically compared with data from an array of sensors, such as potentiometer, accelerometers, and pressure transducers. In the first part of our assessment, we compare the wedge entry depth and velocity obtained through PIV with the results obtained from the potentiometer and accelerometers. Next, we compare the reconstructed pressure and force from PIV with data from pressure transducers and accelerometers. Our results demonstrate the feasibility of PIV in the study of water entry problems, highlighting critical advantages of this non-invasive approach.
