The Slotted Blade Axial-Flow Blower

reportActive / Technical Report | Accession Number: ADA284605 | Open PDF

Abstract:

The slotted blade applies boundary-layer control to the blades of axial-flow blowers. This offers a means to design axial-flow blowers for higher efficiencies or higher pressure coefficient, or possibly a combination of both. Test data of an experimental blower are presented, indicating blower efficiencies to 94 per cent and stage efficiencies to 96 per cent with high- pressure coefficient corresponding to a maximum flow deflection of about 52 deg.
