| Abstract: | With BJL5 two-stage centrifugal forest fire pump as the research object, based on computational fluid dynamics （CFD）, an analytic model suitable for computation is established to simulate the three-dimensional turbulent flow under different operating modes, obtaining the distribution of basic physic quantities in the fluid field inside the pump. The analysis and prediction of the performance of high-lift forest fire pumps are made , with the result contrasted with the experimental result, exploring the simulation and prediction methods suitable for multi-stage centrifugal pumps. |
