"abstract": "Generally flow behavior in centrifugal fan is observed\nto be in a state of instability with flow separation zones on suction\nsurface as well as near the front shroud. Overall performance of the\ndiffusion process in a centrifugal fan could be enhanced by\njudiciously introducing the boundary layer suction slots. With easy\naccessibility of CFD as an analytical tool, an extensive numerical\nwhole field analysis of the effect of boundary layer suction slots in\ndiscrete regions of suspected separation points is possible. This paper\nattempts to explore the effect of boundary layer suction slots\ncorresponding to various geometrical locations on the impeller with\nconverging configurations for the slots. The analysis shows that the\nconverging suction slots located on the impeller blade about 25%\nfrom the trailing edge, significantly improves the static pressure\nrecovery across the fan. Also it is found that Slots provided at a\nradial distance of about 12% from the leading and trailing edges\nmarginally improve the static pressure recovery across the fan.",
