Abstract
The B2SOLPS0.5.2D code can completely derive measured target asymmetries in edge plasma of small size divertor tokamak (SSDT). SOL flow measurements by the code have been performed in L-mode plasma at various poloidal locations in small size divertor tokamak. The main results of simulations suggest that, the following results: (1) SOLPS0.5.2D simulation predicts \( J_{r}^{{({\text{dia}})}} \times B_{T} \)\( J_{r}^{{({\text{dia}})}} \) is diamagnetic current, BT is normal toroidal magnetic field) force due to the presence of large up-down pressure asymmetries is one of the reasons responsible for observed target asymmetries. (2) The shear of plasma toroidal rotation which is contributed for ITB formation and transition to improved confinement regime is formed near separatrix. The role of centrifugal effect in target asymmetries and SOL flow has been investigated.
