  1. Utilización de la CFD como herramienta de apoyo al estudio inicial de las Turbomáquinas Hidráulicas

    Zamora Parra, Blas; Vicéns Moltó, José Luis
    [EN] The Engineering Education requires that students acquire an appropriate knowledge on a mathematical computational language as well as on a numerical simulation procedure. The computational language of mathematics usually is taught in advanced courses, once that the curriculum mathematical education is mainly completed; in addition, the numerical simulation is usually located late or even in doctoral studies. In this paper, we propose that the Computational Fluid Dynamics (CFD) become to be a teaching-learning tool, instead of a strategic resource only. CFD can be regarded as a transversal skill i.e., as a useful educational tool for the Hydraulic Turbomachines learning, which achieves to overcome some epistemological obstacles...

  2. Uso de simulaciones por ordenador para mejorar la enseñanza en el laboratorio de ingeniería química

    [EN] Virtual labs can be adopted as a complement of the university traditional teaching methodologies. This paper describes the results of a teaching pilot project which enabled the use of a commercial processsimulator (Hysys) in the implementation of five virtual labs related to three important unit operations in Chemical Engineering: liquid-liquid extraction, distillation, and heat exchange. The software provided a new approach to the analysis and interpretation of lab results by students. The educational effectiveness of the implemented project was evaluated through questionnaires, and the results showed that in average more of 85% of the student considered Hysys of great utility in their learning process. Project...

  4. Utilización de laboratorios virtuales para la enseñanza y el aprendizaje de la elasticidad

    Jiménez Mocholí, Antonio José; Lapuebla Ferri, Andrés; Giménez Palomares, Fernando
    [EN] Linear Elasticity is a discipline that studies the elastic solids which generate a mechanical response in linear elastic regime under external forces. In particular, is of special interest to study the stresses and strains at any point of the solid, which is known as the elastic problem. In Elasticity it is necessary to know the so-called state of stress in the differential environment of a point of the elastic solid, and also the associated deformations. To this end, in this paper we present the virtual laboratories TENSIONES and DEFORMACIONES, made with the package Matlab through its graphical user interface (GUI). These two virtual laboratories can represent...

  9. La torsión alabeada como secuencia de infinitos problemas de flexión

    Lázaro, Mario; Ferrer, Ignacio
    [EN] In the present article, a methodology for teaching modeling problem of mixed torsion for thin-walled open sections. The mathematical analogy of warped twist as a problem of Euler-Bernoulli beams is exploited. In fact, the paper proposes to represent the warped torsion differential equation as a perturbation of the pure torsion or also called the Saint-Venant theory. Thus, it is demonstrated that under certain conditions related to the value of the torsional slenderness the response of a beam is the addition of infinite pure warped problems, that is, infinite bending problems, according to the analogy. We call this the asymptotic torsion analogy.

  16. Modelización matemática de sistemas CAD en Edificación

    Falcón Ganfornina, Raúl Manuel
    [EN] There exists a wide range of CAD systems devoted to model three-dimensional objects. Based on an intuitive creation and transformation of basic geometrical objects, the mathematical foundation of such systems is generally unknown to their users. The incorporation of this kind of software in Math classes is a fundamental key to get the attention of students of those degrees for which CAD systems are not only attractive, but also extremely important in the future professional career. The current paper deals with the experience carried out in this regard during the last five years by students of the Building Engineering Degree of the University of Seville....
