A centrifugal impeller is a crucial component of a centrifugal compressor, responsible for increasing the pressure and velocity of the incoming air or gas. It works by converting kinetic energy into pressure energy through rapid rotation. Here's an overview of its key aspects:

Structure and Design:

• Blades: The impeller consists of multiple curved blades mounted on a central hub. The blades are aerodynamically designed to efficiently transfer energy.

• Hub and Shroud: The central part (hub) supports the blades, and a shroud covers the blades' tips, forming a sealed passage.

• Material: Typically made from metals like aluminum, stainless steel, or specialized alloys for strength and durability.
