The Scaling Exponents of Intermittent Passive Scalar Field in Fully Developed Turbulence

抄録

Scaling exponents associated with a passive scalar field in fully developed intermittent turbulence are examined on the basis of a new model, which was previously proposed for the intermittent velocity field, in addition to the lognormal- and β-models. Included are the exponents for the temperature structure function in the inertial-convective region, the moments of the volume-limited average scalar dissipation rate and the moments of the scalar field derivative. Those exponents are compared to the related data obtained by experiments.
