Which of the following is a non-positive displacement type of compressor?
Roots blower
compressor
Screw
compressor
Sliding vane
compressor
Axial flow compressor
Axial flow compressor
Non-positive
displacement compressors, also called as steady flow compressors use dynamic
action of solid boundary for realizing pressure rise. Here fluid is not
contained in definite volume and subsequent volume reduction does not occur as
in case of positive displacement compressors. Axial flow compressor and
centrifugal compressor are examples of non-positive displacement compressors.
Hence, the
correct option is (D).
