<p>The specifications of a vane wheel are determined so that they have the relation of nu >/=-0.857Z1+1.009 (wherein nu =r0/r1, Z1=(r1-r0)/Är1-nt/(2 pi )Ü, r0: inner radius of the vane wheel, r1: outer radius of the vane wheel, n: number of radial vanes, t: thickness of the radial vanes). <IMAGE></p> |
