Axial and centrifugal-type compressors typically fall into the category of rotodynamic compressors.
Term 'rotodynamic compressor' typically refers to a continuous-flow compressor, which uses rotating impellers in order to add velocity and pressure to the gas undergoing compression. Compared to positive displacement type compressors, dynamic compressors are typically smaller in size and create less vibration.
Centrifugal compressors
Centrifugal compressors typically consist of one or more stages. Each stage typically consists of an impeller (rotating element) and a diffuser (stationary element).
In a centrifugal compressor, the gas typically enters the impeller axially and is discharged radially. The gas hurled out radially by the rotating impeller blades. When The gas then flows through the circular chamber (diffuser), following a spiral path where the velocity head of the gas gets converted to pressure head as per Bernoulli’s principle. To put it simply, the impeller imparts kinetic energy to the gas fluid, whereas the diffuser converts part of that kinetic energy into pressure head.
The extent of pressure rise in a centrifugal compressor mainly depends on the rotational speed of the impeller and the impeller size. However, the maximum allowable speed is limited by the strength of the structural material of impeller blades and sonic velocity of the gas. As a result, limitations on maximum achievable pressure rise exist. These limitations are overcome by the use of multistage centrifugal compressors, which are able to compress the gas to desirable pressure using multiple stages of centrifugal compressors operating in series.
