Abstract

In this paper a two-dimensional numerical model is developed for simulation of discontinuous density currents. The model is based on unsteady Reynolds-averaged Navier-Stokes equations and uses a buoyancy-modified k - e closure for the turbulence. The governing equations are solved with a finite-volume, fractional step approach. The model is based on a non-iterative direct implicit method. The sigma coordinate system with staggered grid has been deployed. A second order semi-Lagrangian approach has been used for the main advection terms. The model simulation results on discontinuous saline density currents have been compared with the two-dimensional experimental data. It is demonstrated that a two-dimensional model can reliably predict some features of density current. Comparisons with experimental measurement of the evolution of the current, the horizontal velocity components, and the density distributions have shown favorable agreement.
