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…
Alpha effect and dynamo in density-stratified turbulence with large-scale shear: applications to protoplanetary discs and astrophysical clouds
Igor Rogachevskii, Nathan Kleeorin
A joint effect of the density-stratified turbulence (or inhomogeneous turbulence) and a large-scale shear for arbitrary Mach numbers results in the effect and mean-field dynam…
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…
