We present an analytic study of momentum transport of tokamak plasmas in the vicinity of
minimum safety factor (q) position in reversed magnetic shear configuration. Slab ion
temperature gradient modes with an equilibrium flow profile are considered in this study.
Quasi-linear calculations of momentum flux clearly show the novel effects of q-curvature on
the generation of intrinsic rotation and mean poloidal flow without invoking reflectional
symmetry breaking of parallel wavenumber (⁠ k∥⁠). This q-curvature effect originates from …
