Threedimensional Non-Hydrostatical Model of Water-Air Interaction. Numerical Simulation

Safray A.S., Tkachenko I.V.

The current paper considers the results of the numerical simulations fulfilled with a three-dimensional non-hydrostatical model of water–air interaction, with use of the method of large eddy simulations (LES) for aver-aging the full system of Navier-Stokes equations, and the volume of fluid method (VOF) – for describing water-air interface and their interaction. The results of the numerical simulations on the underwater obstacle over-flow are compared with the laboratory data. The preliminary results of the investigation of internal and free surface wave generation as well as the wave interaction, are presented.
