In this thesis we study a family of numerical schemes solving the shal- low water equations system. These schemes use a Lagrange-projection like splitting operator technique in order to separate the gravity waves and the transport waves. An implicit-explicit treatment of the acoustic system (linked to the gravity waves) allows the schemes to stay s...

The problem in question permeates the fluid induced acoustic levitation, which consists of the introduction of a large amount of pressure waves, resulting from the sound vibration of a high frequency exciter creating a pressure field from a compression film, as a consequence of an opposing force to gravity. It is possible for objects to be suspende...
