| Outline of Final Research Achievements |
We have developed a new, extended fluid model of SOL-divertor plasma with incorporating anisotropy of the plasma ion temperature in order to depict behavior of the SOL-divertor plasma. We found that while in collisional plasma, the ion temperature calculated by using the new model agree with that derived by the conventional model, in collisionless plasma the ion temperature is anisotropic. It was also found that the supersonic flow of the divertor plasma at the sheath entrance can be simulated by using the extended fluid model. We evaluated the viscous term by using the anisotropic ion temperature calculated.
