Basic Thermodynamic Cycles

2020
After making clear the difference between isothermal-duty and non-isothermal-duty regimes, the basic cycles, Joule Thomson, Brayton and Claude, are considered and simply calculated. Emphasis is put on cycle optimisation.

Thermodynamic Cycle Applications

1984
The concept of a cyclic thermodynamic process was introduced in section 1.4, and the Carnot cycle was seen to represent a basic method of continuous heat-work conversion. Certain other cycles with equal or lower efficiency are found to have more acceptable overall features, and these cycles are used for comparative purposes in assessing the performance

THERMODYNAMICS AND ENGINE CYCLES

2003
In this chapter, a brief engine history is presented to trace some of the thermodynamic ideas that are used in modern engines. The ideal gas law and polytropic compression/expansion law are reviewed as lead-ins to cycle analysis. Then the Otto cycle is presented as the ideal model for four-cycle SI engines.

Thermodynamics of Cycles

2016
An important application of thermodynamics is the analysis of power cycles through which the energy absorbed as heat can be continuously converted into mechanical work. A thermodynamic analysis of the heat engine cycles provides valuable information regarding the design of new cycles or a combined cycle for improving the existing cycles, or pushing ...

[Thermodynamic muscle cycles].

Biofizika, 1978
On the basis of the analysis of muscle thermodynamic cycles in terms of the concept of non-equilibrium accumulator of energy some conclusions can be made concerning the character of temperature--entropy relationships. If the redistribution phase proceeds with an essential increase of entropy, the muscle contraction cycle proves to be more advantageous ...

Thermodynamics of the purine nucleotide cycle

Biophysical Chemistry, 2006
Since the standard Gibbs energies of formation are known for all the species in the purine nucleotide cycle at 298.15 K, the functions of pH and ionic strength that yield the standard transformed Gibbs energies of formation of the ten reactants can be calculated.

Thermodynamic cycle analysis for capacitive deionization

Journal of Colloid and Interface Science, 2009
Capacitive deionization (CDI) is an ion removal technology based on temporarily storing ions in the polarization layers of two oppositely positioned electrodes. Here we present a thermodynamic model for the minimum work required for ion separation in the fully reversible case by describing the ionic solution as an ideal gas of pointlike particles.
