CFturbo - Software zum Entwurf von Turbomaschinen: radiale, halbaxiale Pumpen- und Ventilatorlaufräder und Spiralgehäuse
Volutes:
major design steps
1. Volute inlet
- Impeller definition by manual input or import from a CFturbo-impeller file
- Adaptation of design flow rate if specified
- Definition of inlet width and inlet diameter of the volute
2. Radial diffusor design
- Import and adapt impeller parameters
- Free design of widths and diameter relations
- Conventional or pinch-type non-bladed diffuser
- In-compressible or compressible streamline
- Computation of velocity components
3. Volute cross-section shapes
- Rectangular, trapezoid or arc
- Various free-form geometries
- Asymmetric or symmetric
- External and internal
4. Pipe diffuser modeling
- Tangential or radial direction
- Free-form modeling
- Round or rectangular end cross section
- Optionally bend in z-direction
5. Volute shape and cutwater design
- Definition of start angle and wrap angle
- Design by Pfleiderer, Stepanoff or own rules
- Cut-water modeling
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
