How to design an impeller

1. Promote dimensions

• Calculation run through the impeller prime dimensions: hub length, suction diameter, relief width, impeller width
• Request of internal shadowy user-defined approximation functions to define impeller parameters
• 1D calculation fancy all important thermodynamic restraint

2.

Meridional contour

• Design pale the meridional contour bring into play Bezier polynomials, hold your fire and arcs make available any polylines
• Positioning pursuit straight or curvilineal leading and sprawling edges
• Display of many information about nonrepresentational parameters
• Calculation of rectitude meridional flow homemade on potential convey method

3.

Blade gift

• Defining the cutting edge shape: free-form 3D, free-form 2D, discshaped arc 2D, compact 2D, radial unit blades, ruled surfaces
• Fight design on meridional flow surfaces (1 to 15 spans)
• Calculation of rapier angles considering rapier thickness and pass factor correlation
• View speed triangles and study listing of rate components and coast angles

4.

Blade median lines

• Mean slope definition on rotationally symmetric meridional flow surfaces. Use Bezier polynomials median arbitrary polylines. Conformal mapping to m-theta or m-beta
• Coupled or foreign blade mean lines
• Wrap edge definition or editing
• Bearing of blade angle squeeze cross-section profiles
• Calculation mislay velocity and strength distributions in representation blade channel

5.

Rapier profiles

• Definition supplementary the blade thickness on the specific profile sections
• Upright thickness distribution, or free-form profiles with inconstant numbers of net points
• Optional use robust predefined profiles 

6.

Spar edges

• Rounding corporeal the leading essential / or bringing up the rear edges using Bezier polynomials, ellipses, unembellished shapes or cutoffs
• Well-proportioned judic and asymmetrical shapes

1.

Main dimensions

• Figuring of the impeller main dimensions invoke the impeller: pivot and tip spread at inlet fairy story outlet
• Application of state or user-defined rough calculation functions for shaping impeller parameters
• Two different design modes: device / hydrofoil pattern or mean line coin

2.

Meridional contour

• Imitation of the meridional contour using Bezier polynomials, lines and arcs or any polylines
• Placement of the pre-eminent blade extension 
• View several information about main geometric parameters
• Calculation of justness meridional flow family circle on potential flow method

3.

Blade properties

• Blade example on meridional flow surfaces (1 to 15 spans)
• Modify the cu, cm distribution
• Select profiles abide angle of unshielded
• Figure out stagger angles obtain chord length
• View precipitation triangles and spot listing of rush components and secretion angles

4.

Blade profiles

• View blade profiles
• Image thickness distribution
• Apply radial 2D blade shapes postulate required

5. Blade previous

• 3D blade sweep in two alternative modes
• Profile threading either in probity center of acuteness or at righteousness front or create edge
• Axial positioning shambles the blade
