Intrinsic rotation and residual stress in full-f ITG turbulence simulations*

Intrinsic rotation of tokamak plasma is of interest for macroscopic stability and understanding and control of transport. To study the toroidal rotation generated by flux-driven turbulence, we have performed full-f flux-driven ITG simulations using XGC1p code, which self-consistently evolves the profile of ion temperature, parallel flow and poloidal flow. The growth of net co-current flow with values of $u_{||}/v_{th}\sim $5\% is observed with no-slip boundary condition. The residual stress is identified by applying external torque which cancels out the intrinsic rotation. Also, correlation analysis between stress, turbulence intensity, ExB shear, and k-parallel symmetry breaking are performed.
