Title:

An Empirical Scaling of theThermal Diffusivity Applicable to Both L-and H-Mode Discharges

Date of publication:

Feb. 1990

Key words:

L-mode, H-mode, Energy Confinement

Abstract:

An empirical scaling of the thermal diffusivity has been constructed which fits well with most of the key observations of steady-state heat transport in tokamaks. This scaling also agrees with observed dynamical transport phenomena and suggests interesting future experiments.
