DIRECT NUMERICAL SIMULATION OF PARTICLE-DRIVEN GRAVITY CURRENTS

Abstract

Particle-driven gravity currents are examined by means of two-dimensional numerical simulations based on highly accurate integration schemes for the fluid-phase equations. Two different approaches are employed to describe the particulate phase, namely a Eulerian treatment and a Lagrangian particle-tracking technique. Good agreement is demonstrated between the two approaches for small particle Stokes numbers.
