A study of structures with intense vorticity in isotropic turbulence

Seminar Room 2, Newton Institute Gatehouse


The characteristics of vortex structures having vorticity occupying the high amplitude tail of the distribution of vorticity amplitudes in homogeneous, isotropic turbulence are investigated. The geometries and vorticity distributions within these structures are determined by use of data obtained from the results of a 1024 cubed DNS at Re_lamda = 433 residing in a Johns Hopkins web-based public database. Of particular interest are (1) the connection between the observed superexponential tail for the vorticity amplitude distribution and these local intense structures and (2) the dynamics that yields such structures.
