Abstract

In this paper sloshing of water in rectangular containers is extensively analysed. Two different mathematical models are employed, the Reynolds Averaged Navier-Stokes equations and the Shallow Water equations. RANSe are solved by means of a semi-implicit formulation of the well established MAC method, SWe are solved by using an algorithm developed in the framework of gas dynamics for hyperbolic equations. In order to validate the mathematical models, experimental tests have been carried out using a 0.5m breadth open tank in periodic roll motion. Numerical results by RANSe compare fairly well in the whole range of cases investigate
