Introduction:
The energy transfer process in a compressor refers to the conversion of mechanical energy into fluid energy. This process can be either continuous or intermittent, depending on the type of compressor. In this case, we are comparing reciprocating compressors and axial compressors to determine the nature of energy transfer.
Reciprocating Compressors:
Reciprocating compressors are positive displacement compressors that use a piston-cylinder arrangement to compress the fluid. The energy transfer process in reciprocating compressors is intermittent. This is because the compression of the fluid occurs during the compression stroke when the piston moves from the top dead center to the bottom dead center. The expansion of the fluid occurs during the expansion stroke when the piston moves from the bottom dead center to the top dead center. Therefore, the energy transfer occurs only during these specific strokes, resulting in an intermittent process.
Axial Compressors:
Axial compressors are dynamic compressors that use a series of rotating blades to compress the fluid. The energy transfer process in axial compressors is continuous. This is because the compression of the fluid occurs continuously as it passes through the rotating blades. The blades increase the velocity of the fluid, which in turn increases its pressure. Therefore, the energy transfer process is continuous throughout the operation of the compressor.
Comparison:
Based on the above explanations, we can conclude that the energy transfer process is continuous in an axial compressor and intermittent in a reciprocating compressor. This is because the compression and expansion strokes in a reciprocating compressor occur intermittently, while the compression in an axial compressor occurs continuously.
Conclusion:
In summary, the energy transfer process in a reciprocating compressor is intermittent, while in an axial compressor, it is continuous. This difference is due to the different operating principles of these two types of compressors.
