A pure hydrodynamic instability in shear flows and its application to astrophysical accretion disks
Sujit Kumar Nath, Banibrata Mukhopadhyay
We provide the possible resolution for the century old problem of hydrodynamic shear flows, which are apparently stable in linear analysis but shown to be turbulent in astrophysica…
Emergence of nonlinearity and plausible turbulence in accretion disks via hydromagnetic transient growth faster than magnetorotational instability
Sujit K. Nath, Banibrata Mukhopadhyay
We investigate the evolution of hydromagnetic perturbations in a small section of accretion disks. It is known that molecular viscosity is negligible in accretion disks. Hence, it…
Origin of nonlinearity and plausible turbulence by hydromagnetic transient growth in accretion disks: Faster growth rate than magnetorotational instability
Sujit Kumar Nath, Banibrata Mukhopadhyay
We investigate the evolution of hydromagnetic perturbations in a small section of accretion disks. It is known that molecular viscosity is negligible in accretion disks. Hence, it…
Cross-correlation Aided Transport in Stochastically Driven Accretion Flows
Sujit Kumar Nath, Amit K. Chattopadhyay
Origin of linear instability resulting in rotating sheared accretion flows has remained a controversial subject for long. While some explanations of such non-normal transient growt…
Magnetohydrodynamic stability of stochastically driven accretion flows
Sujit Kumar Nath
We investigate the evolution of magnetohydrodynamic perturbations in presence of stochastic noise in rotating shear flows. The particular emphasis is the flows whose angular veloci…
Magnetohydrodynamic stability of stochastically driven accretion flows
Sujit K. Nath, Banibrata Mukhopadhyay, Amit K. Chattopadhyay
We investigate the evolution of magnetohydrodynamic/hydromagnetic perturbations in the presence of stochastic noise in rotating shear flows. The particular emphasis is the flows wh…
