Numerical simulations of ion temperature gradient driven turbulence are carried out to investigate the parametric dependence of ion thermal transport on the reduced gyro-radius and on the local safety factor. Whereas the simulations show a clear proportionality of the conductivity to the gyro-radius, the dependence on the safety factor cannot be represented as a simple power law like the one exhibited by the empirical scaling laws.
