Starting from the fundamental relations relying upon the first and second law of thermodynamics, the cycles with no overall external work are examined in this paper. The restricted conditions to which such systems must satisfy under pre-defined assumptions, are determined. Some of these cycles, which exhibit internal irreversibilities of mechanical nature (cicli dissipativi) are studied in detail; as an instance of application for cycles with a recirculating fluid, the case of the single-phase thermosyphon is analyzed.

Abstract
Starting from the fundamental relations relying upon the first and second law of thermodynamics, the cycles with no overall external work are examined in this paper. The restricted conditions to which such systems must satisfy under pre-defined assumptions, are determined. Some of these cycles, which exhibit internal irreversibilities of mechanical nature (cicli dissipativi) are studied in detail; as an instance of application for cycles with a recirculating fluid, the case of the single-phase thermosyphon is analyzed.File in questo prodotto:
