Vertical temperature gradient of the ocean as perspective source of renewable energy [PDF]

open access: yesE3S Web of Conferences
In our research we studied the efficiency of converting low-grade heat into electrical energy. The studied cycle is based on sulphuric acid solutions separation in temperature gradient and further electricity generation in concentration galvanic cell. In

A Posteriori Multiobjective Self-Adaptive Multipopulation Jaya Algorithm for Optimization of Thermal Devices and Cycles

open access: yesIEEE Access, 2019
This paper presents the multiobjective optimization aspects of three thermal devices and two thermodynamic cycles. The thermal devices considered are two-stage thermoelectric cooler, heat pump, and a plate-fin heat exchanger.

Multi-criteria/comparative analysis and multi-objective optimization of a hybrid solar/geothermal source system integrated with a carnot battery

open access: yesCase Studies in Thermal Engineering
Among the different electrical energy storage technologies, the Carnot batteries are promising options with low specific cost that do not suffer from geographical limitations and power-capacity coupling.

An analysis of a thermal power plant working on a Rankine cycle: A theoretical investigation

open access: yesJournal of Energy in Southern Africa, 2017
Today, most of the electricity produced throughout the world is from steam power plants. However, electricity is being produced by some other power generation sources such as hydropower, gas power, bio-gas power, solar cells, etc.

Maximum power of a two-dimensional quantum mechanical engine with spherical symmetry [PDF]

open access: yesarXiv, 2019
We study two-dimensional quantum Carnot engines of spherical symmetry by considering the case of a particle on the surface of a sphere of changing radius. The Carnot cycle is built allowing the state of the system to change with the specific constrains discussed in Bender's work for Carnot cycles. After studying the Carnot cycle, we maximize the output

Carnot's Cycle and Efficiency of Heat Engines [PDF]

open access: yesNature, 1925
ON p. 326 of NATURE for August 29 appears an abstract of a paper by Dr. J. S. Haldane, which he read before the Institution of Mining Engineers on June 16. In this paper he has “thrown to the winds” the usual academic teaching in regard to the efficiency of a Carnot cycle, and has put forward a claim that another cycle has a greater efficiency.
