- 摘要:
- 诱导轮叶型的设计应尽可能减少静压降，并保证叶片的负荷分布均匀，减轻叶片的汽蚀破坏。利用CFD技术分析了阶梯壳体和叶片打孔对诱导轮叶片负荷的影响，计算结果表明这些措施都可以降低叶片前缘的负荷。相比较于叶片打孔，阶梯壳体更加有助于降低叶片前缘的负荷，在一定程度上提高诱导轮汽蚀性能。最后，通过基于混合模型的汽蚀计算验证了上述结论的正确性。
- 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 .
