Abstract

Numerical analysis on the divertor experiments in JFT-2M tokamak is made by the use of the two-dimensional time-dependent simulation code. The plasma in the scrape-off layer (SOL) and divertor region is solved for the given particle and heat sources from the main plasma, Λp and Qt. The effects of the direction of the toroidal magnetic field is studied. It is found that the heat flux, which is proportional tob × ▽Ti, influences the divertor plasma conspicuously, but has only a small effect on the plasma parameters on the midplane in the framework of the fluid model. With inclusion of the b × ▽Ti, term for the radial heat flux, the behavior of the divertor plasma observed in the experiments is explained at least qualitatively.
