Abstract

Centrifugal fans are widely used in order to move air or other gases in ducts. As exact as possible manufacturing of fan is required in order to ensure long time of operation and desired flow parameters. In the article evaluation of influence of unevenly spaced blades onto flow parameters of impeller is considered. Thanks to usage of numerical simulation, few different configuration of blades inaccuracies could be compared with basic ideal case. Received results suggests that inaccuracies in circumferential blade spacing influences flow pattern across impeller and changes flow parameters of fan. It is interesting that in few cases efficiency of impeller is higher than in basic solution, but in fact such situation cannot been accepted since in these cases non-uniform fluid force distribution can cause higher vibrations of fan. In general, differences of efficiency are small what suggests that influence of unevenly spaced blades onto flow parameters can be in many cases neglected.
