Lagrangian chaos, Eulerian chaos, and mixing enhancement in converging–diverging channel flows
1996
Physics of Fluids
A study of Lagrangian chaos, Eulerian chaos, and mixing enhancement in converging-diverging channel flows, using spectral element direct numerical simulations, is presented. The time-dependent, incompressible Navier-Stokes and continuity equations are solved for laminar, transitional, and chaotic flow regimes for 100рReр850. Classical fluid dynamics representations and dynamical system techniques characterize Eulerian flows, whereas Lagrangian trajectories and finite-time Lagrangian Lyapunov
