Computational fluid dynamics (CFD) models in the learning process of Hydraulic Engineering

Abstract

ABSTRACT:In this article, we show the ability to use sophisticated computational fluid dynamics (CFD) models as simple and useful tools in the learning process for Fluid Mechanics and Hydraulic Engineering topics. Specifically, we present a comparison between results obtained for a controlled layout simulated both by physical and computational models. This particular experience is based on a Venturi tube. In the laboratory of the Multidisciplinary Center for Fluid Modeling (CMMF), we have implemented a suitable assembly to simulate different Venturi-related phenomena and to take measurements in an intrusion flow forced by the pressure field into the perforated Venturi tube. The same geometry has been reproduced using a CFD code, and both pressure and velocity values have been compared. By doing this comparison, we first provide awareness to our students about the importance of calibration, then show them the agreement between measured and computed values, and finally design a methodology for students to visualize pressure and velocity fields by means of a number of graphical displays of the results. This approach has revealed itself to be a powerful tool for them to understand the intricacies of hydraulic topics.

Integration of numerical and physical experiments to enhance student learning experience

“…In most of the universities, CFD is mainly being used as an aid to enhance learning in fluid mechanics and heat transfer courses. Educators such as Lopez et al points out that CFD is a powerful tool in the teaching of fluid mechanics and other related engineering courses as it allows easy comprehension of phenomena through visualization of pressure and velocity fields. This view has also been shared by other authors .…”

Teaching Sprinkler Irrigation Engineering by a Spreadsheet Tool

“…Thus, from a pedagogical point of view, conceptualization and practices would allow teachers to uphold their responsibility to shape highly qualified professionals. Classroom lectures, laboratory and field experiments, and technology supplies remain as complementary pathways for engineering significant learning [10][11][12]. However, the technological aspect has become more relevant, particularly in recent decades, due to its permanent and continuous upgrades [13].…”

A teaching–learning method based on CFD assisted with matlab programming for hydraulic machinery courses

“…In Hydraulic Machinery, it can be stated that improving education has received so far only a limited attention. With regard to Hydraulic Engineering topics, López et al described how a methodology of comparing data collected experimentally with a commercial CFD model could be implemented in order to improve the learning process for Hydraulic Engineering problems. Alves de Sousa et al presented a new learning system for a hydroelectric energy production unit by using virtual reality techniques.…”
