Carnot, Stirling, Ericsson stochastic heat engines: Efficiency at maximum power
O. Contreras-Vergara, N. Sánchez-Salas, G. Valencia-Ortega +1
This work obtains the efficiency at maximum power for a stochastic heat engine performing Carnot-like, Stirling-like and Ericsson-like cycles. For the mesoscopic engine a Brownian…
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…
Local and global stability analysis of a Curzon-Ahlborn model applied to power plants working at maximum -efficient power
G. Valencia-Ortega, S. Levario-Medina, M. A. Barranco-Jiménez
The analysis of the effect of noisy perturbations on real heat engines, working on any steady-state regime has been a topic of interest within the context of Finite-Time Thermodyna…
Energetic optimization considering a generalization of the ecological criterion in traditional simple-cycle and combined cycle power plants
S. Levario-Medina, G. Valencia-Ortega, M. A. Barranco-Jiménez
The fundamental issue in the energetic performance of power plants, working both as traditional fuel engines and as combined cycle turbine (gas-steam), lies in quantifying the inte…
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…
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…
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…
