Zentrifugalverdichter

A Zentrifugalverdichter, also known as a centrifugal compressor, is a dynamic compressor that uses a rotating impeller to increase the pressure of a gas. The gas enters the impeller at its center and is accelerated outwards by centrifugal force. As the gas leaves the impeller, it enters a diffuser, which is a stationary component that slows down the gas and converts its kinetic energy into pressure energy. This process is continuous, with gas flowing through the compressor and its pressure rising.

The main components of a Zentrifugalverdichter are the impeller, the diffuser, and the casing. The impeller is the rotating part that imparts energy to the gas. Diffusers can take various forms, such as vaneless diffusers or vaned diffusers, each with its own efficiency characteristics. The casing encloses the other components and directs the gas flow.

Zentrifugalverdichter are widely used in various applications due to their high efficiency, reliability, and relatively compact size. Common applications include turbochargers in internal combustion engines, refrigeration and air conditioning systems, industrial gas compression, and aircraft engines. They are particularly well-suited for applications requiring high flow rates and moderate pressure increases. The performance of a Zentrifugalverdichter is typically characterized by its pressure ratio and flow rate, which are influenced by factors such as impeller speed, impeller diameter, and diffuser design.
