Shaft Length: Shaft length

Counter Flow¶

The counter flow impeller is composed of 3 parts:

Part 1 : Trapezoid blade part connected to shaft
Part 2 : Rectangle blade part connected to part 1. A vertical square connected to this part is dimensioned based on the Part 2 width
Shaft

Number Blades: Number of blades
Thickness: Thickness of blade solids
Part 1 Angle: Angle of part 1 of blade
Part 1 Length: Length of part 1 trapezoid
Part 1 Width 1: Base width of part 1 trapezoid
Part 1 Width 2: Tip width of part 1 trapezoid
Part 2 Length: Length of part 2 rectangle
Part 2 Width: Width of part 2 rectangle
Part 2 Angle: Angle of part 2
Shaft Diameter: Shaft diameter

Helical Ribbon¶

The helical ribbon is a rectangle that is extruded along a helical path. The rectangle dimensions are controled by Blade Width and Thickness. The helix parameters are also available.

Number Blades: Number of blades
Number of Turns: Number of helix turns. May be a fractional value.
Blade Width: Width of blade
Helix Pitch: Height of helix for every 1 turn
Helix Diameter: Diamter of helix
Thickness: Thickness of blade

High Solidity Hydrofoil (HSH)¶

This impeller represents a notional high solidity hydrofoil with large blades. The leading edge tip of each blade is bent slightly.

Number Blades: Number of impeller blades
Diameter: Diameter [Model Units]
Shaft Length: Shaft length. Set to zero to disable [Model Units]
Shaft Diameter: Shaft diameter [Model Units]
Blade Angle: Blade angle

Low Solidity Hydrofoil (LSH)¶

This impeller represents a notional low solidity hydrofoil. The leading edge tip of each blade is bent slightly.

Number Blades: Number of hydrofoil impeller blades
Diameter: Diameter of the hydrofoil impeller [Model Units]
Shaft Length: Shaft length. Set to zero to disable [Model Units]
Shaft Diameter: Shaft diameter [Model Units]
Blade Angle: Hydrofoil Blade angle [deg]

Pitch Blade¶

Number Blades: Number of impeller blades
Diameter: Diameter of impeller. The length of each blade is Diameter / 2.
Thickness: Thickness of blades
Pitch Angle: Blade angle [deg]
Diameter Chord Ratio: The diameter of the impeller divided by the width of the blade. Controls the aspect ratio.
Shaft Length: Shaft length. Set to zero to disable
Shaft Diameter: Shaft diameter

Retreat¶

Diameter: Diameter
Number Blades: Number of blades
Hub Diameter: Hub diameter
Blade curve radius: Radius of blade curve
Blade height: Blade height
Blade Thickness: Blade thickness

Sawtooth¶

This impeller is built using a flat circular disk as the hub, with “teeth” around the perimeter of the hub. Each tooth starts out as a flat rectangular surface with a length equal to “Tooth Length” and width based on the number of teeth around the circumference of the hub. The tooth is then rotated about one of its corners by the angle Blade Angle, then a bend is applied. The blade angle controls the oblique bend angle for each tooth. The tooth is then joined with the hub.

Diameter: Diameter [Model Units]
Number Teeth: Number of teeth
Blade Angle: Blade Angle. Determines oblique bend angle of each tooth. As values approach zero, no bend will be realized [deg]
Tooth Length: Length of each tooth
Shaft Length: Shaft length. Set to zero to disable [Model Units]
Shaft Diameter: Shaft diameter [Model Units]
