Abstract	We have developed global ITG (Ion Temperature Gradient Driven Drift Wave) turbulence code to investigate anomalous ion transport in tokamak plasmas. The gyro-fluid model is extended to incorporate acc...urate form of neoclassical viscosity. Firstly, we have performed the linear analysis of ITG mode using this code. The dependence of growth rate on various parameters are examined. Next, we have done nonlinear simulations to investigate neoclassical effect on zonal flow damping and saturation amplitude of ITG turbulence. The weak dependence of saturation level on neoclassical viscosity is found in our simulations.show more
