How does an axial flow compressor operate?

An axial flow compressor operates by taking in ambient air and then increasing its velocity and pressure as it moves through a series of rotating and stationary blades. The design of the compressor allows air to flow parallel to the axis of rotation, hence the term "axial."

As the air passes through the rotating blades, it gains kinetic energy, which translates to an increase in velocity. Simultaneously, the stationary blades, often referred to as stators, further compress the air by converting this kinetic energy into pressure energy. This process ensures that as the air flows through the stages of the compressor, both its pressure and velocity are increased, making it ready for combustion in gas turbine applications.

This understanding is essential in the operation of gas turbines, where efficient air compression is critical for optimal performance and efficiency.
