Abstract

In this study, we presents the results of hydrodynamic impact tests performed with the shock machine at ENSTA Brittany, by integrating a device allowing to generate bubbles in the tank. During these tests, the average void fractions considered are between 0.35 and 1.1%. Our results highlight a significant reduction of the impact force with the increase of the void fraction.
