While kinetic helicity is not Galilean invariant locally, it is known [Moffatt, J. Fluid Mech. 35,
117 (1969)] that its spatial integral quantifies the degree of knottedness of vorticity field lines …

Helicity plays a key role in the evolution of vortex structures and turbulent dynamics. The
helicity dynamics and vortex structures in streamwise-rotating channel turbulence are …

Many issues pioneered by Jackson Herring deal with how nonlinear interactions shape
atmospheric dynamics. In this context, we analyze new direct numerical simulations of …

For settling the problem with rotating turbulence modelling, a quasi-dynamic one-equation
subgrid-scale (SGS) model is proposed in this paper. Considering the key role of the joint …

This study investigates the characteristics of submerged vortices in an intake sump through
a combination of numerical simulations, experimental validations, and advanced modeling …

The spatio-temporally varying turbulent energy cascade dynamics in forced homogeneous/
periodic turbulence is investigated with direct numerical simulations (DNS) and Helmholtz …

Developed turbulent flows in which the intervention of external forces is fundamentally
important at scales where the inertial range should exist are quite common. Then the …
