Experiments on Air Compression with an Isothermal Piston for Energy Storage

Energies, 2019
Air is usually compressed adiabatically in the compressor. As the operating speed of compressors can be several thousand rpm, heat generated during compression cannot be sufficiently transmitted to the environment in such a short time.
