【Abstract】 A calculation model is established for the corrugation and annular flow field of a stratification injection allocator by using 3D Max and it is put into VR environment of PHOENICS and based on the actual geometric size of the allocator, κ-ε turbulent calculating model is used for numerical calculation of water medium flow field by using orthogonal and detail grid under coordinate system. The curves of velocity distribution and pressure distribution of flow field are presented. The simulation results of 3 types of corrugation and annular flow fields are contrasted and analyzed. The result shows that thecorrugation and annular flow field is closely related with the shape of flow channel.更多还原
