Energy conversion theorems for some linear steady-states
L. A. Arias-Hernandez, G. Valencia-Ortega, F. Angulo-Brown +1
One of the main issues that real energy converters present, when they produce effective work, is the inevitable entropy production. Within the context of Non-equilibrium Thermodyna…
Energetic optimization effects in single resonant tunneling --nanoconverters
G. Valencia-Ortega, L. A. Arias-Hernandez
Several models of thermionic energy nanoconverters have been proposed to study the transport phenomena that take place in electronic devices. For example, in resonant tunneling jun…
The -Compromise Function as a criterion of merit to optimize irreversible thermal engines
S. Levario-Medina, L. A. Arias-Hernandez
Several authors have proposed out of equilibrium thermal engines models, allowing optimization processes involving a trade off between the power output of the engine and its dissip…
Temperature profile of an assemblage of non-isothermic linear energy converters
S. Gonzalez-Hernandez, L. A. Arias-Hernandez
In this paper, a proposal is presented to determine the temperature profile obtained for an assemblage of non-isothermal linear energy converters (ANLEC) published by Jimenez de Ci…
Thermal optimization of Curzon-Ahlborn heat engines operating under some generalized efficient power regimes
S. Levario-Medina, G. Valencia-Ortega, L. A. Arias-Hernandez
In order to establish better performance compromises between the process functionals of a heat engine, in the context of finite time thermodynamics (FTT), we propose some generaliz…
Thermoelectric Thomson's relations revisited for a linear energy converter
S. Gonzalez-Hernandez, L. A. Arias-Hernandez
In this paper we revisit the thermocouple model, as a linear irreversible thermodynamic energy converter. As is well known, the linear model of the thermocuple is one of the classi…
Thermodynamic properties of diatomic molecules systems under anharmonic Eckart potential
G. Valencia-Ortega, L. A. Arias-Hernandez
Due to one of the most representative contributions to the energy in diatomic molecules being the vibrational, we consider the generalized Morse potential (GMP) as one of the typic…
Thermodynamic optimization of an electric circuit as a non-steady energy converter
G. Valencia-Ortega, L. A. Arias-Hernandez
Electrical circuits with transient elements can be good examples of systems where non--steady irreversible processes occur, so in the same way as a steady state energy converter, w…
Connection between maximum-work and maximum-power thermal cycles
Julian Gonzalez-Ayala, L. A. Arias-Hernandez, F. Angulo-Brown
We propose a new connection between maximum-power Curzon-Ahlborn thermal cycles and maximum-work reversible cycles. This linkage is built through a mapping between the exponents of…
A first--order irreversible thermodynamic approach to a simple energy converter
L. A. Arias-Hernández, R. T. Paez-Hernández, F. Angulo-Brown
Several authors have shown that dissipative thermal cycle models based on Finite-Time Thermodynamics exhibit loop-shaped curves of power output versus efficiency, such as it occurs…
