Let us assume that condition is ideal and there is no slip and no pre whirl. The most fundamental configuration of a centrifugal compressor is the straight-through design. Diffuser gradually reduces the air velocity. It is available in market from low to high capacities. Multiple compression trains are normally supplied in parallel to achieve total flow and head requirements of a specific application. The centrifugal air compressor is a dynamic compressor which depends on transfer of energy from a rotating impeller to the air. We will see here two cases and velocity diagram will be different for these two cases. The Principle of Centrifugal Compression: Aero-Dynamics.
