Granular column collapse: The role of particle size polydispersity on the velocity and runout

Geophysical mass flows involve particles of different sizes, a property termed polydispersity. The granular column collapse is simplified experiment for studying transitional flows. Our research focuses on the role that polydispersity has velocity and runout distance dry immersed columns, undergoing numerical experimental study. results highlight does not have strong effect columns. On contrary, sequence immerse columns strongly depend level.
