Nonlinear mode coupling and energetics of driven magnetized shear-flow turbulence
B. Tripathi, A. E. Fraser, P. W. Terry +3
To comprehensively understand saturation of two-dimensional (D) magnetized Kelvin-Helmholtz-instability-driven turbulence, energy transfer analysis is extended from the traditio…
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…
Mechanism for Sequestering Magnetic Energy at Large Scales in Shear-Flow Turbulence
B. Tripathi, A. E. Fraser, P. W. Terry +2
Straining of magnetic fields by large-scale shear flow, generally assumed to lead to intensification and generation of small scales, is re-examined in light of the persistent obser…
The impact of magnetic fields on momentum transport and saturation of shear-flow instability by stable modes
A. E. Fraser, P. W. Terry, E. G. Zweibel +2
The Kelvin-Helmholtz (KH) instability of a shear layer with an initially-uniform magnetic field in the direction of flow is studied in the framework of 2D incompressible magnetohyd…
A New Optimized Quasihelically SymmetricStellarator
A. Bader, B. J. Faber, J. C. Schmitt +12
A new optimized quasihelically symmetric configuration is described that has the desir-able properties of improved energetic particle confinement, reduced turbulent transportby 3D…
Role of stable modes in driven shear-flow turbulence
A. E. Fraser, M. J. Pueschel, P. W. Terry +1
A linearly unstable, sinusoidal shear flow is examined in the gyrokinetic framework in both the linear and nonlinear regimes. In the linear regime, it is shown that th…
