Hidden symmetries and nonlinear constitutive relations for tight-coupling heat engines

open access: yesNew Journal of Physics, 2015
Typical heat engines exhibit a kind of homotypy: the heat exchanges between a cyclic heat engine and its two heat reservoirs abide by the same function type; the forward and backward flows of an autonomous heat engine also conform to the same function ...

Performance Analysis and Optimization of a Solar Powered Stirling Engine with Heat Transfer Considerations

open access: yesEnergies, 2012
This paper investigates the optimization of the performance of a solar powered Stirling engine based on finite-time thermodynamics. Heat transference in the heat exchangers between a concentrating solar collector and the Stirling engine is studied.

Application of Stirling Engine Type Alpha Powered by the Recovery Energy on Vessels

open access: yesPolish Maritime Research, 2020
The Stirling engine is a device in which thermal energy is transformed into mechanical energy without any contact between the heat carrier and the working gas enclosed in the engine. The mentioned feature makes this type of engine very attractive for the

The Thermodynamics of Heat Engines [PDF]

open access: yesNature, 1903
THIS is a very good specimen of that sort of book which is an amplification of the lecture notes of a professor who has carefully prepared problems for students. We may not always like the way in which he introduces the subject to his pupils, and we may say that it is unphilosophical and even cryptic, and sometimes too brilliant, but such comments are ...

A single-atom heat engine [PDF]

open access: yesScience, 2016
Making a teeny tiny engine Steam locomotives, cars, and the drinking bird toy all convert heat into useful work as it cycles between two reservoirs at different temperatures. Usually, the working substance where the heat-work conversion occurs is a liquid or a gas, consisting of many molecules. Roβnagel et al.

Cooling Cyclic Air of Marine Engine with Water-Fuel Emulsion Combustion by Exhaust Heat Recovery Chiller

open access: yesEnergies, 2021
The fuel efficiency of marine diesel engine as any combustion engine falls with raising the temperature of air at the suction of its turbocharger. Therefore, cooling the engine turbocharger intake air by recovering exhaust gas heat to refrigeration ...
