摘　　要：本文针对低温余热能量回收透平装置设计了一种新型的可调节叶片喷嘴机构(Rotatable Vaned Nozzle,RVN),该设计具有结构新颖、可靠性高的特点。在调节结构设计的基础上,采用CFD方法对叶片喷嘴内流动特性进行了数值分析,研究了不同转动角度对喷嘴性能的影响。A Novel Rotatable Vaned Nozzle （RVN） is deslgne（1 tor a turbine equinment which used in low-temperature exhaust heat energy recovery system in this paper. The RVN has the characteristics of novel structure and high reliability. Based on the structure design of RVN, the flow in the RVN is simulated by using CFD method, and the effect of different rotated angles on nozzle performance is also investigated.
