Turbophoresis of inertial particles in inhomogeneous turbulence generated by oscillating grids
E. Elmakies, O. Shildkrot, N. Kleeorin +2
Turbophoresis in inhomogeneous turbulent flows leads to the formation of large-scale nonuniform particle number density distributions of inertial particles. This effect is associat…
Experimental study of turbulent thermal diffusion of inertial particles in a convective turbulence forced by oscillating grids
E. Elmakies, O. Shildkrot, N. Kleeorin +2
We investigate the phenomenon of turbulent thermal diffusion of inertial solid particles in laboratory experiments with convective turbulence forced by one or two oscillating grids…
Large-scale clustering of inertial particles in a rotating, stratified and inhomogeneous turbulence
Nathan Kleeorin, Igor Rogachevskii
We develop a theory of various kinds of large-scale clustering of inertial particles in a rotating density stratified or inhomogeneous turbulent fluid flows. The large-scale partic…
Theory of the kinetic helicity effect on turbulent diffusion of magnetic and scalar fields
Igor Rogachevskii, Nathan Kleeorin, Axel Brandenburg
Kinetic helicity is a fundamental characteristics of astrophysical turbulent flows. It is not only responsible for the generation of large-scale magnetic fields in the Sun, stars,…
Helicity effect on turbulent passive and active scalar diffusivities
Axel Brandenburg, Petri J. Käpylä, Igor Rogachevskii +1
Turbulent flows are known to produce enhanced effective magnetic and passive scalar diffusivities, which can fairly accurately be determined with numerical methods. It is now known…
On dissipation time scales of the basic second-order moments: the effect on the Energy and Flux-Budget (EFB) turbulence closure for stably stratified turbulence
Evgeny Kadantsev, Evgeny Mortikov, Andrey Glazunov +2
The dissipation rates of the basic second-order moments are the key parameters playing a vital role in turbulence modelling and controlling turbulence energetics and spectra and tu…
