| Abstract: | In view of the disadvantages of relatively higher power and lower efficiency for a type of automotive engine cooling water pump, a new design method which aiming at semi-closed-cycloidal type impeller is put forward based on the theory of centrifugal pump and computational fluid dynamics（CFD）. The pump pressure-velocity coupling hydrodynamic model is also accomplished. Combining with test, the flow, efficiency and power of the new impeller and the previous impeller are analyzed. The final results indicate that power of the new impeller is reduced significantly and its efficiency is improved as well. |
