Abstract
Multifractal analysis based on the energy dissipation ε and the enstrophy Ω in isotropic turbulence is made by using high-resolution direct numerical simulation of turbulence with the number of grid points up to 2048 3. The analysis shows that the singularity exponents α and α that characterize the intermittencies associated with ε and Ω, respectively, agree well with each other in the inertial subrange. This result is consistent with logεr and logΩr correlating well with each other for the scale r in the inertial subrange, where the subscript denotes the local average over a cubic domain of size r.
