Momentum conservation and gyrokinetic simulations of toroidal rotation

摘要

The global behavior of fusion plasmas- in magnetic confinement devices is Critically associated to large-scale mean flows. In. particular, toroidal flows impact both turbulent transport, through the saturation of turbulence by sheared flows; and MHD stability by increasing the threshold for the onset of resistive wall modes. In view of predicting the toroidal rotation in future fusion devices such as ITER, where; external momentum input will, be small, accurate simulations of momentum transport are crucial.
