出口弯管对前向离心通风机性能影响的研究
Effect on the Performance of the Forward Centrifugal Fan with Outlet Bent Pipe
摘要
Abstract
The experiments and numerical simulationsare conducted to investigate the effect on the performance of a centrifugal fan (9-26No4A) with outlet bent pipe.The results show that the performance of the fan declines significantly when the fan is directly connected with either a forward or a backward outlet bent pipe,especially at large flowrates.But only slight difference on the fan performance is found between the two cases.Moreover,little changes are observed when a straight pipe with length less than or equal to 3.5Dh is installed between the fan outlet and the outlet bent pipe.关键词
