Energy conversion and storage
In this study, a new finned piston compressor that is characterized by increased heat transfer area and coefficient has been designed, analyzed, manufactured and experimentally tested. Results show that the heat transfer along one cycle has increased in the finned compressor by 32 times compared to a classic piston compressor. In addition, although the volumetric efficiency decreased slightly in the finned compressor (8%), the exergetic efficiency was observed to increase from 55.1% in a classic piston to 78.4% in the finned piston.
