- Abstract:
- The blade shape design of inducer should depress the drop of static pressure, ensure the load uniformity on the blade and alleviate destroy of cavitation. The effects of case with steps and punching at blades on inducer blade load are analyzed by using CFD technology. The results show that the measures can decrease the load of blade leading edge. Compared with punching on the blades, it is more easy for the case with steps to reduce the load of blade leading edge and improve the cavitation performance of inducer. The cavitation calculation based on the mixture model was performed, and the above conclusion was confirmed .
