Kees This paper presents our approach for the computation of free-surface/rigid-body interaction phenomena with emphasis on ship hydrodynamics. We adopt the level set approach to capture the free-surface. The rigid body is described...

To compute the hydrodynamic forces, a direct integration method is employed, where the fluid stresses are integrated over the particles’ surfaces. For the purpose...

In this method, the hydrodynamic force is used to divert the gas flow in a cavity located in the breech to avoid contact with the optical window and prevent it from being contaminated. To verify the effectiveness...
