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…
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…
Gyrokinetic Studies of Microinstabilities in the RFP
Daniel Carmody, M. J. Pueschel, P. W. Terry
An analytic equilibrium, the Toroidal Bessel Function Model, is used in conjunction with the gyrokinetic code GYRO to investigate the nature of microinstabilities in a reversed fie…
