Abstract
Numerical simulations of high Reynolds number flows in the unit driven cavity have been performed. The system is shown to become unsteady at Re = 8125 and chaotic at Re = 17,000. In between this range the syste m switches between periodic and quasi-periodic states with step-wise c hanges in period. A passive concentration field and passive tracer par ticles are introduced into the flow at its asymptotic state to show th e effects of chaos on mixing. (C) 1998 Elsevier Science Inc.
