Analysis of azimuthal magnetorotational instability of rotating MHD flows and Tayler instability via an extended Hain-Lust equation
Rong Zou, Joris Labarbe, Yasuhide Fukumoto +1
We consider a differentially rotating flow of an incompressible electrically conducting and viscous fluid subject to an external axial magnetic field and to an azimuthal magnetic f…
Stability and flow fields structure for interfacial dynamics with interfacial mass flux
Daniil V. Ilyin, Yasuhide Fukumoto, Sergei I. Anisimov +2
We analyze from a far field the evolution of an interface that separates ideal incompressible fluids of different densities and has an interfacial mass flux. We develop and apply t…
Dynamical model of a turbulent round jet through conservation of mass flux and power
Fermin Franco, Yasuhide Fukumoto
We propose a family of two-phase-fluid models for a full-cone turbulent round jet that describe its dynamics in a simple but comprehensive manner with the apex angle of the cone be…
Mass entrainment rate of an ideal momentum turbulent round jet
Fermín Franco Medrano, Yasuhide Fukumoto, Clara M. Velte +1
We propose a two-phase-fluid model for a full-cone turbulent round jet that describes its dynamics in a simple but comprehensive manner with only the apex angle of the cone being a…
Relabeling symmetry in relativistic fluids and plasmas
Yohei Kawazura, Zensho Yoshida, Yasuhide Fukumoto
The conservation of the recently formulated relativistic canonical helicity [Yoshida Z, Kawazura Y, and Yokoyama T 2014 J. Math. Phys. 55 043101] is derived from Noether's theorem…
Local instabilities in magnetized rotational flows: A short-wavelength approach
Oleg N. Kirillov, Frank Stefani, Yasuhide Fukumoto
We perform a local stability analysis of rotational flows in the presence of a constant vertical magnetic field and an azimuthal magnetic field with a general radial dependence. Em…
Instabilities of rotational flows in azimuthal magnetic fields of arbitrary radial dependence
Oleg N. Kirillov, Frank Stefani, Yasuhide Fukumoto
Using the WKB approximation we perform a linear stability analysis for a rotational flow of a viscous and electrically conducting fluid in an external azimuthal magnetic field that…
A unifying picture of helical and azimuthal MRI, and the universal significance of the Liu limit
Oleg N. Kirillov, Frank Stefani, Yasuhide Fukumoto
The magnetorotational instability (MRI) plays a key role for cosmic structure formation by triggering turbulence in the rotating flows of accretion disks that would be otherwise hy…
