Numerical predictions of the poloidal E × B drift in EAST

The effects of poloidal E × B drift in EAST are study with a one-dimensional fluid code. The transport equations are solved in the poloidal direction with the radial particle and energy influxes as source terms. The simulation results show that the effects of poloidal E × B drift on the plasma density and temperature are stronger in high recycling case than in detached case. With the core-edge density increasing, the tendency of pouter/pinner is to decrease for normal BT and to increase for reversed BT. The ratios of the outer/inner particle and energy fluxes increase with PSOL for normal BT and decrease with reversed BT. The degree of divertor asymmetries due to the poloidal E × B drift is reduced at low power and high density for both normal and reversed BT, as expected.
