Nonmodal growth and optimal perturbations in magnetohydrodynamic shear flows
Adrian E. Fraser, Alexis K. Kaminski, Jeffrey S. Oishi
In astrophysical shear flows, the Kelvin-Helmholtz (KH) instability is generally suppressed by magnetic tension provided a sufficiently strong streamwise magnetic field. This is of…
Three-Dimensional Shear-Flow Instability Saturation via Stable Modes
B. Tripathi, P. W. Terry, A. E. Fraser +2
Turbulence in three dimensions (D) supports vortex stretching that has long been known to accomplish energy transfer to small scales. Moreover, net energy transfer from large-sc…
Near-cancellation of up- and down-gradient momentum transport in forced magnetized shear-flow turbulence
B. Tripathi, A. E. Fraser, P. W. Terry +2
Visco-resistive magnetohydrodynamic turbulence, driven by a two-dimensional unstable shear layer that is maintained by an imposed body force, is examined by decomposing it into dis…
Resistive instabilities in sinusoidal shear flows with a streamwise magnetic field
Adrian E. Fraser, Imogen G. Cresswell, Pascale Garaud
We investigate the linear stability of a sinusoidal shear flow with an initially uniform streamwise magnetic field in the framework of incompressible magnetohydrodynamics (MHD) wit…
