vinkelrotorer
Vinkelrotorer, literally “angle rotors” in Swedish, refer to a class of rotor designs in which the blades or vanes are mounted at a fixed angle relative to the plane perpendicular to the rotor axis. This angular offset causes the flow entering or leaving the rotor to acquire an axial component in addition to the tangential component produced by rotation, thereby altering the velocity triangle of the working fluid.
The operating principle of vinkelrotorer is to convert mechanical energy into a modified flow field by directing
Construction and design characteristics commonly include blade profiles optimized for the intended fluid and speed range,
Advantages of angled rotor designs include potential improvements in flow control and efficiency for specific operating
