air stream blocking the passage

motion of air at sonic velocity

unsteady periodic and reversed flow

air stream not able to follow the blade contour

centrifugal compressors deliver prac-tically constant pressure over a considerable range of capacities

Axial flow compressors have a sub-stantially constant delivery at variable pressures

centrifugal compressors have a wider stable operating range than axial flow compressors

axial flow compressors are bigger in diameter compared to centrifugal type
