Thermodynamic Cycles with Phase Change
2019Though thermodynamic cycles have already been introduced in Sect. 17.2, this chapter covers cycles, in which the working fluid is subject to phase changes. If a system after several changes of state finally reaches the initial state, it is called a thermodynamic cycle. Thus, all state values reach their initial value, i.e.

Thermodynamic cycles and the calculation of pKa
Chemical Physics Letters, 2003Abstract A theoretical equation for the calculation of p K a based on a proton transfer reaction between the acid and one water molecule is derived using the general chemical equilibrium relationship. The present result is compared with two equations recently used that were based on thermodynamic cycles, but predict different p K a ’s. It is shown

A thermodynamic cycle with a quasi-isothermal expansion
International Journal of Hydrogen Energy, 1998Abstract The combustion of hydrogen and oxygen makes feasible a steam re-heating by mixing rather than by surface exchange. In such a way the use of several re-heaters is possible as well as the increase of re-heating temperature. The performances of steam power-plants with a large number of super-heaters (5–15) have been analyzed.

Performance of Quantum Thermodynamic Cycles
2018Quantum cycles are the microscopic version of the macroscopic thermodynamic cycles, such as the Carnot cycle or the Otto cycle. The quantum Otto cycle consists of four-strokes, two adiabats and two isochores. The equations for the dynamics on the adiabats and isochores are derived from first principles and illustrated for a working medium consisting of

On Thermodynamic Cycles for Detonation Engines
2012Detonation engines are considered to potentially yield better performance than existing turbo-engines in terms of improved thermodynamic efficiency, simplicity of manufacture and operation, and high thrust-to-weight or thrust-to-volume ratio, amongst other advantages.
