Abstract:

Nowadays, the search for new active and constructive methodologies in learning is one of the pedagogical objectives in universities and other educational institutions. In the degrees taught at the ETSEAMN, the phenomena associated with heat transport and the underlying physics are studied. In the master classes, the phenomenon of this energy balance in a one-dimensional system is explained. In the present work, the analytical solution is developed and analyzed at the same time that a numerical model is shown with which the same solution is obtained. One of the advantages of using numerical tools is that more complex solutions can be obtained, even if the corresponding analytical solution does not exist or is not known, which is useful for engineering students. Therefore, to demonstrate the applications and possibilities of this work, it is shown that it is easy to change the boundary conditions, geometry or dimension in the system and the mathematical model, and solve it by applying a numerical solution method, being more complex for students in its analytical form. Therefore, a simple way of modifying the degrees of freedom of the same problem applied in the case of a vegetable subjected to a heat treatment is shown so that the students can understand how these modifications affect the solution and that dimensionally some problems can be simplified in order to contextualize them. The development of PoliformaT platform implemented in the Universitat Politècnica de València facilitates the use of these new teaching models that combine traditional on-site laboratory assignments with other learning assignments carried out autonomously online by students.
