Radial and mixed-flow
pump / ventilator impellers
Overview
- nq-area approx. 10 ... 120
- Calculation of the main dimensions: hub, suction port and impeller diameter, inlet and outlet width
- Closed and semi-open impeller with user-defined positioning of the leading edge
- User-defined meridian shapes (Bezier splines or straight line+arc) with checking of curvature and cross-sectional area progression, static moment
- Blade angle calculation with estimation of decreased output
- Simple curved 2D blades (prismatic, circular arc, straight) or spatially curved 3D-blades (free-form, radial fibre) with checking of blade angle progression
- Blade thickness distribution and rounding of the blade leading and/or rear edge (Bezier splines, ellipse or simple)
- 3D representation
