Prediction of supercavitation shapes for a wide range of Froude numbers
International Journal of Naval Architecture and Ocean Engineering, 2022 In this study, we developed an inviscid model to predict the shape of supercavitation in a wide range of Froude numbers (Fr) based on the potential theory suggested by Logvinovich (1973). Visualization experiments were carried out in a cavitation tunnel,
