Interplay between geostrophic vortices and inertial waves in precession-driven turbulence

F. Pizzi, G. Mamatsashvili, A. J. Barker +2

The properties of rotating turbulence driven by precession are studied using direct numerical simulations and analysis of the underlying dynamical processes in Fourier space. The s…

Convective, absolute and global azimuthal magnetorotational instabilities

A. Mishra, G. Mamatsashvili, V. Galindo +1

We study the convective and absolute forms of azimuthal magnetorotational instability (AMRI) in a Taylor-Couette (TC) flow with an imposed azimuthal magnetic field. We show that th…

Aerodynamic sound of turbulent time-developing shear layer as the outcome of the flow linear non-modal instability

George Khujadze, David Gogichaishvili, George Chagelishvili +3

The aim of this paper is to substantiate the importance of non-normality of shear flow linear operators and its consequence -- the non-modal dynamics of the perturbations -- in the…

The timestep constraint in solving the gravitational wave equations sourced by hydromagnetic turbulence

A. Roper Pol, A. Brandenburg, T. Kahniashvili +2

Hydromagnetic turbulence produced during phase transitions in the early universe can be a powerful source of stochastic gravitational waves (GWs). GWs can be modelled by the linear…

The dynamo effect in decaying helical turbulence

Axel Brandenburg, Tina Kahniashvili, Sayan Mandal +3

We show that in decaying hydromagnetic turbulence with initial kinetic helicity, a weak magnetic field eventually becomes fully helical. The sign of magnetic helicity is opposite t…

Quasi-two-dimensional nonlinear evolution of helical magnetorotational instability in a magnetized Taylor-Couette flow

G. Mamatsashvili, F. Stefani, A. Guseva +1

Magnetorotational instability (MRI) is one of the fundamental processes in astrophysics, driving angular momentum transport and mass accretion in a wide variety of cosmic objects.…

Dynamics of homogeneous shear turbulence: A key role of the nonlinear transverse cascade in the bypass concept

G. Mamatsashvili, G. Khujadze, G. Chagelishvili +3

To understand the self-sustenance of subcritical turbulence in spectrally stable shear flows, we performed direct numerical simulations of homogeneous shear turbulence for differen…

Classes of hydrodynamic and magnetohydrodynamic turbulent decay

Axel Brandenburg, Tina Kahniashvili

We perform numerical simulations of decaying hydrodynamic and magnetohydrodynamic turbulence. We classify our time-dependent solutions by their evolutionary tracks in parametric pl…

Infrasound generation by tornadic supercell storms

M. Akhalkatsi, G. Gogoberidze

Acoustic wave generation by turbulence in the stratified, moist atmosphere is studied. It is shown that in the saturated moist air turbulence in addition to the Lighthill's quadrup…
