High-fidelity simulations of particle-laden gravity currents in non-axisymmetric lock-exchange configurations are presented and compared with more conventional channelized and axysymmetric lock-exchange configurations. We limit our investigations to gravity currents over a flat bed in which density differences are small enough for the Boussinesq approximation to be valid. The concentration of particles is described in an Eulerian fashion by using a transport equation combined with the incompressible Navier-Stokes equations. Our non-axisymmetric results highlight similarities and differences with axisymmetric and channelized lock-exchange configurations and show that the dynamics of the current and final deposition maps are significantly influenced by the geometry of the initial reservoir.
