Conversion of poloidal flows into toroidal flows by phase space structures in trapped ion resonance driven turbulence

چکیده
A theory to describe the conversion of poloidal momentum into toroidal momentum by phase space structures in trapped ion resonance driven turbulence is presented. In trapped ion resonance driven turbulence, phase space structures are expected to form and can contribute to transport by exerting dynamical friction. Toroidal momentum flux by dynamical friction is calculated. It is shown that dynamical friction exerted on trapped ion granulations can mediate momentum transfer between poloidal and toroidal flows. The conversion coefficient is calculated as measurable that can be validated in present devices. Conversion of poloidal flows into toroidal flows by phase space structures 2

Isotope effects on turbulent transport and entropy transfer processes in toroidal plasmas
In this article, additional discussions on the nonlinear entropy transfer between turbulence and zonal flows are given for the isotope ion mass effects on the trapped-electron-mode (TEM) driven turbulent transport shown in Ref. 1. Spectral analyses with the triad entropy transfer function reveal that the case with heavier isotope ions indicates a relatively smaller negative transfer (from zonal...

Global gyrokinetic simulations have revealed an important nonlinear flow generation process due to the residual stress produced by electrostatic turbulence of ion temperature gradient ITG modes and trapped electron modes TEMs . In collisionless TEM CTEM turbulence, nonlinear residual stress generation by both the fluctuation intensity and the intensity gradient in the presence of broken symmetr...

Experimental investigations has elucidated on the complex dynamics of the low to high (L-H) plasma confinement mode transition. Evidence of interactions between the the turbulence driven E⃗ × B⃗ zonal flow oscillation or Geodesic Acoustic Mode (GAM) [1], turbulence and the mean equilibrium flows during this transition was found. Furthermore, periodic modulation of flow and turbulence level with t...
متن کاملMagnetic Topology Effects on Alcator C-Mod Flows
The effect of magnetic topology on ion and impurity flows in a tokamak is considered by investigating the consequences of (i) the reversal of toroidal and poloidal magnetic fields and currents, (ii) a switch from lower to upper X-point operation, (iii) poloidal magnetic field or plasma current reversal, and (iv) toroidal magnetic field reversal. The general symmetries associated with magnetic t...
متن کاملThree-dimensional Mhd Simulations of Radiatively Inefficient Accretion Flows
We present three-dimensional MHD simulations of rotating radiatively inefficient accretion flows onto black holes. We continuously inject magnetized matter into the computational domain near the outer boundary and run the calculations long enough for the resulting accretion flow to reach a quasi-steady state. We have studied two limiting cases for the geometry of the injected magnetic field: pu...
