Abstract
Experimental results on probability distribution functions (pdf’s) of full dissipation ε, enstrophy ω2, and enstrophy generation ω i ω js ij in two different turbulent flows: turbulent grid flow (Reλ=74) and turbulent jet center (Reλ=880) demonstrate the possibility of universal behavior of the pdf’s of these quantities.
