Dissipation field asymmetry and intermittency in fully developed turbulence
Experimental study of high Reynolds number turbulence provides additional evidence that asymmetry of turbulence is related to the intermittency. The refined similarity hypothesis (RSH), on the other hand, connects the intermittency of the longitudinal velocity increments with that of the dissipation field, implying in particular that the dissipation field should be asymmetric as well. The asymmetry of the latter is indeed found in these experiments. In addition, the study of the dissipation field asymmetry provides us with quantitative estimations of the deviations from the RSH.
