Is the Kelvin Theorem Valid for High-Reynolds-Number Turbulence? [PDF]
, 2006 The Kelvin-Helmholtz theorem on conservation of circulations is supposed to hold for ideal inviscid fluids and is believed to be play a crucial role in turbulent phenomena, such as production of dissipation by vortex line-stretching.

Reynolds-number effects and anisotropy in transverse-jet mixing [PDF]
, 2006 Experiments are described which measured concentration fields in liquid-phase strong transverse jets over the Reynolds-number range 1.0×10^3 ≤ Rej ≤ 20×10^3. Laser-induced-fluorescence measurements were made of the jet-fluid-concentration fields at a jet-
