Study on the Performance of a Sirocco Fan (Flow Around the Runner Blade)

[摘要] Initially in this research, effects of blade inlet and outletangles on the performance were considered by measuringperformances. Twelve impellers with various blade angleswere used for the measurements. The most suitable inlet andoutlet angles and the inclination angle were acquired. Then,measurements on the inlet and outlet flows and their axialand circumferential distributions were taken for various operatingconditions at the various measuring positions. Theturning angles through the blade were calculated from thesemeasured results. The inlet and outlet flows of the siroccofan are not uniform around the circumference. The distributionsof the flow have some relations with the developmentof flow in the inlet part and in the casing. Discussions weremade on the flow to have a improved performance.
