Overview

• Definition of inflow (outflow of impeller)
• Design rule by PFLEIDERER (const. swirl) or STEPANOFF (const. velocity)
• Design of cut-water
• Different cross section shapes: Rectangle, Trapezoid, symmetric/asymmetric circle, free-form (Bezier)
• Tangential or radial diffusor with round or rectangular end cross section
• 3D representation
