FIG. 4.

Simulated deuterium heat flux vs for NSTX shot at .

Image of FIG. 5.
FIG. 5.

(a) The deuterium poloidal velocity vs normalized minor radius from simulation and local neoclassical prediction. (b) The radial electric field obtained from simulation and radial force balance.

Image of FIG. 6.
FIG. 6.

(a) The deuterium poloidal velocity vs normalized minor radius. Compared to Fig. 5(a), the new dashed curve is the local prediction modified by orbit shearing effect. The new solid curve also includes orbit squeezing effect. (b) The radial electric field obtained from simulation and radial force balance.

FIG. 7.

Corrections to deuterium poloidal velocity due to orbit shearing (dashed curve) and orbit squeezing (solid curve) nonlocal effects.

Image of FIG. 8.
FIG. 8.

(a) The carbon poloidal velocity vs normalized minor radius. The dashed black curve is the simulation result. (b) The radial electric field obtained from the simulation and the radial force balance.
