Scaling laws for rockfall impact fragmentation emerging from diverse lithologies
Alvaro Vergara, Sergio Palma, Raul Fuentes
Impact-induced fragmentation is a fundamental dissipative process in geosciences, yet its stochastic nature makes predicting debris evolution a persistent challenge. Here, we intro…

Drag coefficient for irregularly shaped grains: rotational dependence at high Reynolds numbers
Álvaro Vergara, Deheng Wei, Raúl Fuentes
The nature and behaviour of the drag coefficient of irregularly shaped grains within a wide range of Reynolds numbers is discussed. Using computational fluid dynamics (CFD) tools,…
