Drift reduced Landau fluid model for magnetized plasma turbulence simulations in BOUT++ framework
Ben Zhu, Haruki Seto, Xue-qiao Xu +1
Recently the drift-reduced Landau fluid six-field turbulence model within the BOUT++ framework has been upgraded. In particular, this new model employs a new normalization, adds a…
Generalized slab universal instability and its appearance in pair plasma
Ben Zhu, Manaure Francisquez, Barrett N. Rogers +1
A generalized linear dispersion relation of electromagnetic slab universal modes is derived, taking into account arbitrary ion charge state, electron finite Larmor radius (FLR) eff…
Fluid & Gyrokinetic turbulence in open field-line, helical plasmas
Manaure Francisquez, Tess N. Bernard, Ben Zhu +3
Two-fluid Braginskii codes have simulated open-field line turbulence for over a decade, and only recently has it become possible to study these systems with continuum gyrokinetic c…
Gyrokinetic theory of slab universal modes and the non-existence of the Gradient Drift Coupling (GDC) instability
Barrett N. Rogers, Ben Zhu, Manaure Francisquez
A gyrokinetic linear stability analysis of a collisionless slab geometry in the local approximation is presented. We focus on universal (or entropy) modes driven by…
