Working of centrifugal compressor

Working of centrifugal compressor 
by

1 Answer

Answer :

Working of centrifugal compressor : When the air passes through the rotating impeller it experiences force or work which is performed by centrifugal forces. The work input takes place as an increase in pressure and velocity or speed of the air flow through the impeller. The air flow looses it’s velocity after entering in the diffuser section. The diffuser is actually a fixed or static component that escorts the air flow when it leaves the impeller. This loss in velocity eventually results in an additional increase of pressure. The impeller and the diffuser contributes about 65% and 35% of the total pressure developed or produced in the compressor.
