Compressors are instrumental pieces of equipment used in several industries to increase the pressure of a fluid. This fluid is most commonly a gas, such as oxygen, nitrogen, and methane. These versatile devices come in a variety of designs and can be scaled to meet the needs of numerous applications, both large and small. At the simplest level, compressors are a type of turbomachinery, and much of their functioning will be familiar to those involved with turbines. Further, a solid understanding of the operating principles of a compressor will aid in the comprehension of similar turbomachinery. In this blog, we will focus on the nuances associated with centrifugal compressors, including their design, operating principle, and applications.
