Volutes:
major design steps
1. Volute inlet
- Definition of inlet width and inlet diameter of the volute
- Positioning of volute relative to other components
2. Volute cross-section shapes
- Rectangular, trapezoid or arc
- Various free-form geometries
- Asymmetric or symmetric
- External and internal
3. Volute shape
- Definition of start angle and wrap angle
- Design by Pfleiderer, Stepanoff or own rules
4. Pipe diffuser modeling
- Tangential or radial direction
- Free-form modeling
- Round or rectangular end cross section
- Optionally bend in z-direction
- Length of diffuser
5. Cutwater
- Cut-water modeling
- Simple mode (construction by Bezier spline)
- Fillet mode
6. 3D-view
- Dynamic 3D-representation (rotate, move, zoom)
- Partial views
- Export of CAD model
7. Data export
- Export of points, curves and surfaces
- Neutral formats like IGES, STEP, DXF supported
- Direct interfaces to major CAD/CAE/CFD-systems
- Special export formats available on customer request
