Abstract

Strong acceleration intermittency in fluid turbulence is interpreted in the context of different supports for local enstrophy and dissipation by introducing a new decomposition of acceleration. This paper proposes a simple Lamb Vortex Model that captures statistical fea-tures of acceleration, such as probability density functions, flatness factors, and correlation coefficients, observed in the direct numerical simulation of homogeneous isotropic turbulence.
