摘要
A three-dimensional, fluid code is used to study the scaling of ion thermal transport caused by ion-temperature-gradient-driven (ITG) turbulence. The code includes toroidal effects and is capable of simulating the whole torus. It is found that both close to the ITG threshold and well above threshold, the thermal transport and the turbulence structures exhibit a gyro-Bohm scaling, at least for plasmas with moderate poloidal flow.
