As an illustration, we solve free surface problems for centrifuged granular piles. These have recently been considered as an affordable and simple way to experiment with powders and dust in reduced gravity environments such as on the Moon or on Mars.}, number={1}, journal={SIAM REVIEW}, author={Gordon-Wright, Rachael and Gremaud, Pierre A.}, year={2013}, pages={168–184} }
