Particle-laden gravity currents: The lock-release slumping regime at the laboratory scale

This study investigates the early slumping regime of particle-laden gravity currents from full-depth dam-break releases, combining laboratory experiments and two-fluid simulations. By systematically exploring the parameter space, it highlights the influence of the bottom slope, particle volume fraction and particle settling velocity on the flow dynamics.

Abstract

This study investigates the early slumping regime of particle-laden gravity currents from full-depth dam-break releases, combining laboratory experiments and two-fluid simulations. By systematically exploring the parameter space, it highlights the influence of the bottom slope, particle volume fraction and particle settling velocity on the flow dynamics.
