On the Tchen's theory of discrete particles dispersion: Can dense discrete particles disperse faster than fluid particles?
In the framework of the Tchen's theory of the dispersion of discrete particles in turbulrnt flows, it is shown that discrete particles can disperse faster than fluid particles, even if the Lagrangian r.m.s. velocity for discrete particles is smaller than the Lagrangian r.m.s. velocity for fluid particles. Examples are given, assuming a Frenkiel's family of Lagrangian correlations for fluid particles velocities.
