Diagramas termodinámicos interactivos de los ciclos de potencia atkinson y brayton con regeneración: diagramas termodinámicos interactivos del ciclo de potencia atkinson.

Abstract

In the present document a detailed explanation of the development of the computer tool corresponding to the Atkinson power cycle is made. For its development it is necessary to previously analyze information corresponding to the cycle. The software is developed through the Python programming language with the help of its libraries, highlighting the Tkinter library with which the graphical interface is developed. For its efficient development, an adequate methodology is used to describe the whole development process. The software allows the input of 4 variables, necessary to determine the thermodynamic behavior of the cycle in its 4 states and delivers as main results 3 interactive diagrams corresponding to the energy, entropy, and exergy of the cycle. To know if the results delivered by the software are correct, the validation is performed through an error analysis comparing the results obtained by the analytical method, which uses the thermodynamic tables of Cengel, and with the help of the TermoGraf software. Two sensitivity analyses are also performed, in the first one the compression ratio is varied and in the second one the temperature in state 3, in this way the behavior of the cycle is analyzed and how its properties change from state to state, as these variables intervene in the thermal performance.
