Healing of magnetic islands in stellarators by plasma flow
Recent experiments from the Large Helical Device (LHD) indicate that the plasma flow can play a primary role in “healing” vacuum magnetic islands in stellarators. The observed elimination of magnetic islands tends to occur at low collisionality and high plasma β. A model explaining this phenomenon is developed reminiscent of ’mode locking/unlocking’ physics of tokamak and reversed field pinch e...
متن کاملPlasma flow healing of magnetic islands in stellarators*
Recent experiments from the Large Helical Device (LHD) indicate that the plasma flow can play a primary role in eliminating magnetic islands produced in the vacuum configuration of conventional stellarators. The observed island healing occurs at a critical plasma β that varies with plasma collisionality. A model explaining this phenomenon is developed based upon self-consistent island evolution...
متن کاملZonal flow dynamics and control of turbulent transport in stellarators.
The relation between magnetic geometry and the level of ion-temperature-gradient (ITG) driven turbulence in stellarators is explored through gyrokinetic theory and direct linear and nonlinear simulations. It is found that the ITG radial heat flux is sensitive to details of the magnetic configuration that can be understood in terms of the linear behavior of zonal flows. The results throw light o...
متن کاملEffect of Wing Sweep Angle on the Vortex Interaction of a Tail-Wing Configuration
The goal of this investigation is to study the effect of wing sweep angle on the horizontal wing-body- tail configurations in subsonic flow. For this purpose, a series of wind tunnel tests were conducted on a model having a moveable horizontal tail and a wing planform with different sweep angles. Tests were performed at different tail deflection angles. Static surface pressure distribution over...
