Abstract

Transient dynamics of containers partially filled with liquid J. Gerrits, A.E.P. Veldman Department of Mathematics, University of Groningen, The Netherlands Abstract From a computational point of view, fluid behaviour under micro-gravity conditions is more complicated than under terrestrial conditions: the fluid has a tendency to undergo large topological changes, requiring an accurate and robust method for free-surface advection. Moreover, the fluid is often contained in a cavity (e.g. satellite) that itself is moving; not only because of external forces (e.g. manoeuvring thrusters on a satellite), but also under influence of the fluid motion: the dynamics of the solid-body motion and the liquid motion are coupled. In the paper a method is presented for simulating coupled liquid-solid dynamics under micro-gravity conditions (although the method also works in a terrestrial environment). The liquid dynamics is solved by discretising the Navier-Stokes equations on a Cart
