Diagramas termodinámicos interactivos de los ciclos de potencia otto y diesel : diagramas termodinámicos interactivos del ciclo diesel.

Abstract

Design a software to obtain Interactive thermodynamical diagrams for Diesel using Python with two calculation methods for numeric solving, exact method and approximate method using the assumptions for each one, Coolprop’s library provides all the necessary properties of air to calculate using exact method; the graphic interface in this software is done using Tkinter library from Python as principal graphic tool, the thermodynamical diagrams are done using Matplotlib library, considering this library as the best option for result visualization at interactive and esthetic sense. This software shows numerical results of Diesel cycle solution with the Energy, entropy and exergy interactive diagrams, these interactive diagrams have been created by the authors of this project under the supervision of Project tutor Ing. Miguel Ortega. The output software has a friendly graphical interface for the user and offers the possibility to vary initial data and get immediate results. The analysis from influence of properties at results helps to understand the importance of volumetric ratios of Diesel (compression ratio and cut-off ratio), because these ratios define the thermal efficiency of the Diesel cycle.
