On ion temperature gradient and parallel velocity shear instabilities
The local dispersion relation for waves with frequencies in the range of the diamagnetic frequencies v j * and parallel wave numbers satisfying the conditions k ics /ve*;1 and qRk i@1 has been obtained in the framework of kinetic theory keeping the equilibrium density, temperature, and parallel velocity gradients into account ( j is the species index, qR the connection length, and cs the speed ...
متن کاملGyrokinetic Particle-In-Cell Global Simulations of Ion-Temperature-Gradient and Collisionless-Trapped- Electron-Mode Turbulence in Tokamaks
The goal of thermonuclear fusion research is to provide power plants, that will be able to produce one gigawatt of electricity. Among the different ways to achieve fusion, the tokamak, based on magnetic confinement, is the most promising one. A gas is heated up to hundreds of millions of degrees and becomes a plasma, which is maintained or confined in a toroidal vessel by helical magnetic field...

متن کاملDescriptive Analysis of Frontal Symmetric Instabilities without Background Temperature Gradient
We examine the SI effects and Bachman’s SI Parameterization in a two-fronts LES simulation. The domain, governed by periodic horizontal temperature profile, consists of a Geostrophic Stable front and a Geostrophic Unstable front. In the study, we find that the Bachman’s SI Parameterization is not good enough to reproduce the Reynolds stress and the SI turbulent buoyancy transport in the LES sim...
متن کاملKinetic and fluid simulations on steady and quasisteady states of slab ion temperature gradient driven turbulence
Anomalous transport caused by plasma turbulence has long been a central subject in research on the magnetic confinement fusion. Ion temperature gradient (ITG) driven turbulence is considered to be responsible for the anomalous ion heat transport in a core of magnetically confined plasmas. Kinetic and fluid simulation studies on the ITG turbulence transport have been actively done in the last de...
