Flow of Three-Phase mixtures

Lavas and magmas are made of a mixture of molten rock, crystals of different sizes, and gas bubbles. This makes magmas and lavas complex fluids, that behave in different ways depending, for instance, on the fraction each of these components take.

We investigate the flow of three-phase magmas on a range of length scales:

We use dam-break experiments to observe the flow of multiphase suspensions and evaluate their rheology. To see better inside the flows, we conduct the experiments inside an MRI machine!
