Statistics of the Energy Dissipation Rate and Local Enstrophy in Turbulent Channel Flow
Peter E. Hamlington, Dmitry Krasnov, Thomas Boeck +1
Using high-resolution direct numerical simulations, the height and Reynolds number dependence of higher-order statistics of the energy dissipation rate and local enstrophy are exam…
Lagrangian studies in convective turbulence
Joerg Schumacher
We present high-resolution direct numerical simulations of turbulent three-dimensional Rayleigh-Benard convection with a focus on the Lagrangian properties of the flow. The volume…
Direct Assessment of Vorticity Alignment with Local and Nonlocal Strain Rates in Turbulent Flows
Peter E. Hamlington, Jörg Schumacher, Werner J. A. Dahm
A direct Biot-Savart integration is used to decompose the strain rate into its local and nonlocal constituents, allowing the vorticity alignment with the local and nonlocal strain…
Lagrangian dispersion and heat transport in convective turbulence
Joerg Schumacher
Lagrangian studies of the local temperature mixing and heat transport in turbulent Rayleigh-Benard convection are presented, based on three-dimensional direct numerical simulations…
Local and Nonlocal Strain Rate Fields and Vorticity Alignment in Turbulent Flows
Peter E. Hamlington, Jörg Schumacher, Werner J. A. Dahm
Local and nonlocal contributions to the total strain rate tensor at any point in a flow are formulated from an expansion of the vorticity field in a local spherical neighborhood of…
