Abstract
We present measurements of the curve of from two-dimensional sections of the "dissipation" field of concentration fluctuations, and from one-dimensional sections of the dissipation field of passive temperature fluctuations, in turbulent jets. The results confirm the universality of the dissipation rate of scalar fluctuations and the applicability of Taylor's hypothesis, and show that the curve of is the same for different components of , that the additive properties of apply to intersections, and that the intermittency exponent of is considerably higher than that for the turbulent kinetic-energy dissipation.
