Axial Compression

Definition - What does Axial Compression mean?

Axial compression is a type of force or pressure exerted on a body causing it to experience shear stress and bending. Axial compression is produced by axial compressors so that natural gas can be pressurized continuously making it easy to flow over long distances in the interstate or intrastate pipelines. Axial compression technology is also used to compress certain liquids so as to keep them pressurized.

Petropedia explains Axial Compression

Axial compression is accounted when gases or liquids flow parallel to the axis of rotation (i.e., axially) in an axial compressor over a series of stages in it through a decreasing tubular area. Axial compression of air or gases or liquids is performed in a wide range of industries such as gas turbines and gas compressors, jet engines, engines used in marine industry, power stations, etc.

An axial flow compression compresses the gases or liquids by first accelerating the matter and then diffusing it to obtain an increase in pressure. The axial compression is achieved when the matter is passed through the row of rotating blades or airfoils of a rotor of an axial compressor and then diffused over to a row of stator that consist of stationary blades. This diffusion action over the stator causes tremendous increase in pressure as well as velocity of the air or gas or liquids passing through it, making such compressors suitable for transporting liquids and gases to transport through long distance pipelines.
