Direct Numerical Simulation of Heavy-Gas Dispersion in a Plane Channel
A direct numerical simulation study of two-dimensional lock-exchange flows in a plane channel is conducted. The simulations are based on the Boussinesq equations where density differences are assumed to be small. The influence of the Reynolds number on the propagation speed of the gravity currents is examined. The simulation results are in good agreement with experimental reference data and theoretical findings.
