Round jet: self-preservation confirmed at every scale
A look back at our Journal of Fluid Mechanics paper (2016): on the axis of a round jet, theory and hot-wire data show complete self-preservation.

Far wake of a square cylinder: a two-term energy budget
A look back at our FSSIC paper: far behind a square cylinder, the turbulent energy brought in by advection is dissipated almost on the spot.

Turbulent dissipation: which approximation to choose?
A look back at my Physics of Fluids paper (2014): in the simulated wake of a square cylinder, which approximations of the dissipation are reliable?

The wake of a heated crossbar: like grid turbulence
A look back at my work presented at THMT7 (Palermo, 2012): simulating the wake of a heated crossbar by LBM and comparing it with grid turbulence.

Localised turbulence and a short contraction: better mixing in a channel
A look back at my work presented at ETC13 (Warsaw, 2011): simulating two pulsed jets in a channel by LBM, and showing the effect of a short contraction.
