Taken impurity radiation and momentum loss in the divertor region into consideration, the applicability of Core-SOL-Divertor(CSD) model to the divertor detachment is investigated. Three solutions for the low recycling state, the high recycling state and the detached state can be obtained from the CSD model. The dependence of the ratio of the decay length for the density (Δn) and temperature (ΔT ) in the SOL region is also examined, and it is found that ΔnT ∼ T80.5 s scaled by the SOL temperature (T s), which is based on the experimental data, has a good potential to reproduce B2-EIRENE results.
