turbinhjul

Turbinhjul is a Swedish term that translates to "turbine wheel" or "impeller" in English. It refers to a rotating component of a turbomachine, such as a turbine or a pump, that is designed to transfer energy between a fluid and the rotating shaft. The design of a turbinhjul is critical to the efficiency and performance of the turbomachine.

In a turbine, the turbinhjul extracts energy from a flowing fluid (like steam, gas, or water) and converts it into rotational mechanical energy. The fluid's kinetic and/or potential energy causes the blades of the turbinhjul to spin. Conversely, in a pump or a compressor, the turbinhjul is driven by a motor and imparts energy to the fluid, increasing its pressure or velocity.

Turbinhjul are typically constructed from materials like steel, aluminum alloys, or composites, chosen for their strength, resistance to corrosion, and ability to withstand high temperatures and rotational speeds. The shape and angle of the blades are precisely engineered based on the specific application, fluid properties, and desired performance characteristics. Common types include axial, radial, and mixed-flow turbinhjul. The development and manufacturing of turbinhjul involve complex aerodynamic and mechanical design principles.
