| Abstract: | Adopting SIMPLE alogrithm,the flowing field of sewerage pump was numerical value emulated using k-ε- Ap turbulence model and tetrahedron non-structure grid in the Descartes reference frame. Through numerical simulation, flow characteristics and distribution rule were gotten on sold particle in sewerage pump,which can supply reference to optimization design of centrifugal sewage pump. |
