共振磁微扰对输运势垒弛豫的控制
Control of Transport-barrier relaxations by Resonant Magnetic Perturbations
摘要:
采用三维整体流体湍流第一性原理数值模拟方法研究了共振磁扰动下托卡马克边缘的输运势垒弛豫振荡。结果表明,共振磁扰动有稳定这些弛豫振荡的效果,这种效果主要是由于修改的压力分布与存在的剩余剩余磁岛链和随机层。
英文摘要:
Transport-barrier relaxation oscillations in the presence of resonant magnetic perturbations are investigated using three-dimensional global fluid turbulence simulations from first principles at the edge of a tokamak. It is shown that resonant magnetic perturbations have a stabilizing effect on these relaxation oscillations and that this effect is due mainly to a modification of the pressure profile linked to the presence of both residual residual magnetic island chains and a stochastic layer.
