Abstract

A regenerative turbine impeller comprises an annular disk having an annular partition wall extending radially therefrom. A first plurality of circumferentially spaced turbine vanes provided on one side of the partition wall radially projecting from the annular disk and have a radial length greater than the partition wall. A second plurality of circumferentially spaced turbine vanes circumferentially spaced about the disk extend radially therefrom and are provided on a second side of the partition wall. The second plurality of vanes rotationally staggered with respect to the first plurality of turbine vanes.
