On the basis of model test,a 2D numerical simulation on the flow field of discharge from surface-bottom outlet on low waterhead and big flux was made by adopting k-εturbulence model and VOF method.

Numerical simulation with the standard k-ε model was performed to study single-phase convective heat transfer at the impinging zone of non-immersed slot jet.

K-ε model was dispersed by the co ntrol-volume method and solved by the SIMPLE algorithm.

Based on the consideration of the dispersed phase interaction with continuous phase, applying the k-ε model and the stochastic trajectory model with to the gas phase and solid phase,the particle motion trajectory was simulated successfully.
