Chaotic Mixing Simulations

Tan BT, Morris P, Thompson MC, Hourigan K, Applied Mathematical Modelling, Vol 22(12), p.p. 1047-1057, 1998

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 system switches between periodic and quasi-periodic states with step-wise changes in period. A passive concentration field and passive tracer particles are introduced into the flow at its asymptotic state to show the effects of chaos on mixing.
