Quantum, cyclic and particle-exchange heat engines
, 2004 Differences between the thermodynamic behavior of the three-level amplifier (a quantum heat engine based on a thermally pumped laser) and the classical Carnot cycle are usually attributed to the essentially quantum or discrete nature of the former.

ISENTROPIC EFFICIENCY OF GAS TURBINE AXIAL COMPRESSORS AND THE OUTDOOR TEMPERATURE EFFECT
Journal of Energy TechnologyThis paper presents the calculation of the isentropic efficiency of a gas turbine axial compressor manufactured by Alstom. Isentropic efficiency shows how much energy is transformed in exergy and how much into anergy. This paper presents the calculation of axial compressor characteristics of an Alstom GT11N2 thermal power plant in Brestanica, Slovenia.
