Abstract
The ion temperature gradient driven mode or ηi-mode turbulence is reinvestigated based on two-component compressible fluid equations with the polarization drift velocity and adiabatic electrons. The scaling of the anomalous ion heat conductivity with magnetic shear s = Ln/L s and the excess of ηi over the critical value ηi,c for marginal stability is found to vary as χi = g(ρs/Ln)(cTi/eB) (ηi - ηi,c)exp(-as), where g≃1 and α≃5. © 1990 American Institute of Physics.
