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
