Abstract:

It has been demonstrated elsewhere that the simple interaction of a two dimensional field of discrete particles traveling on a regular lattice yields large scale behavior closely approximating the continuum Navier-Stokes equations. Numerical experiments have been encouraging, yielding results that seem to represent complex flow fields accurately. Initial investigations into free surface fluid dynamics behaviour shows promise of appropriate flow field and surface wave representation. Experiments involving condensation of a dispersed gas to a free surface liquid, wave oscillations in a closed basin, and an unsteady uniform open channel flow, point out potential problems as well as opportunities.
