Grid turbulence near the grid

Lundi 1er avril 2019, 13h15, ECL salle de réunion I11 bas.

Grid turbulence near the grid

In grid turbulence, not so far behind the grid, an average flow can be observed with a close to sinusoidal velocity profile, corresponding to the wakes behind the grid bars. The kinetic energy of this mean flow decays rapidly and a close to isotropic flow is observed further downstream. We show how these wakes behind the grid-bars influence the down-stream turbulence.
