| 摘 要： | 为了改善高比转速下增压器的涡轮性能，本文为匹配Ｊ６１１０Ｚ柴油机的ＨＩＦ增压器设计了混流涡轮．设计中采用了结合叶轮准三元流动分析的涡轮性能预测新方法．混流涡轮的性能试验结果显示，与径流涡轮相比，混流涡轮流通能力更大，并且能在更低的速度比ｕ／ｃｏ下得到更高的涡轮峰值效率．

| Abstract: | In order to improve turbocharger turbine performance at high specific speed, a mixed-flow turbine was designed for H1F turbocharger that is used in J6110Z diesel. A new turbine performance prediction method combined with quasi three-dimensional rotor flow analysis was used in the design process. The turbine performance experimental results show that the mixed-flow turbine has larger flow capacity and can obtain higher maximum efficiency at lower velocity u/c0 than radial turbine. |
