... Hydrodynamics (SPH) method. The four waves have been selected in order to generate wave shapes just before impact representative of those leading to the largest loads during 2D sloshing model tests for low filling levels or during wave impact tests in flumes. A flip-through impact and three gas-pocket impacts...

... interfacial liquid-vapor phase change and nucleation. The numerical simulation of the piston problem allows us to retrieve the damping phenomena for gas pocket impacts. For a 2D liquid impact test case, a slight amplification of the maximal pressure has been found. Introduction For any project of membrane...

... ABSTRACT: The effect of phase transition during liquid impacts involving entrapped gas pockets might play an important role for fluids close to thermodynamic equilibrium as LNG/NG in tanks of LNG carriers. However, this role is disregarded during Sloshing Model Tests. This issue was addressed...
