Abstract:
R245fa is used as the the working lluid ,the eomputational fuid dynamies( CFD) sofeware FLUENTis adopled,and the standard k-s model is applied in this paper. The guide vanes that blade numbers rangefrom 15 to 27 inereased by 2 and the seling angles range from 24° to 40° inereased by 4° have been numeri.eally studied. The results of computation show that the guide vane’s outlet average circeumferential velocity,outlet average temperature and veloeity coelfieient have greatly improved compared with the original design,when the vane number is 2l and the setting angle is 28°. The blade height that original design llowrate re.quired is got with the linear fitting method in this vane number and setting angle. Research shows that the llowin the channel is in good eondition afler oplimization. This paper may provide a referenee for designing an effi.cient guide vane.
