<p>Title : RADIALLY CURVED AXIAL CROSSECTIONS OF TIPS AND SIDES OF DIFFUSER VANES. Inventor : Kenneth Campbell This invention is proposed further to increase the efficiency of all vaned diffuser types used in centrifugal compressors, without in itself further increasing the overall diameter. The invention is so to curve in radial plane, the axial crossections of vanes from tip to near the throat, so as logically to accommodate the heretofore deleterious effect of the long-recognized highly-arched relative velocity traverse across the impeller exit annulus, a recognition seldom reflected in diffuser structure over the past approximately 49 years of vaned diffuser development.</p> |
