Mixing of passive scalars in viscoelastic turbulent jets and wakes
The figures show passive scalar contours in Newtonian (top) and viscoelastic (bottom) turbulent jets generated by direct numerical simulations (DNS). Initially, the depletion of small scale perturbations by the polymers suppresses the small scale mixing, but later allows the appearance of very large coherent structures that promote the stirring and thus enhance large and intermediate scale stirring.
