摘要：

Experimental results on probability distribution functions (pdf's) of full dissipation epsilon, enstrophy omega2, and enstrophy generation omega(i)omega(j)s(ij) in two different turbulent flows: turbulent grid flow (Re(lambda)=74) and turbulent jet center (Re(lambda)=880) demonstrate the possibility of universal behavior of the pdf's of these quantities.
