Gyro-Bohm Scaling of Ion Thermal Transport from Global Numerical Simulations of Ion-Temperature-Gradient-Driven Turbulence
The ion gyroradius scaling of ion thermal transport caused by ion-temperature-gradient-driven turbulence is studied with a global fluid simulation code in three-dimensional toroidal geometry. It is found that the effective conductivity scales like the ion gyroradius (gyro-Bohm scaling).
