Evaluación de la influencia de la calidad de mallado en simulaciones CFD

Abstract

Abstract: Different simulations were carried out applying the Ansys student software in its Fluent tool, to evaluate the variation of the results when simulations are carried out with different sizes and types of mesh. The main problem posed in the research is to find a type of mesh that is ideally adapted to the proposed geometry to guarantee real results. For this, investigations were carried out to be able to apply meshing techniques in order to save computational resources and time, guaranteeing the quality of the results. In the research methodology, it was proposed to evaluate a hydraulic channel with a Creager-type weir. The results obtained indicated that, after studying the type of geometry, meshing techniques can be applied, which guarantees us real results in less analysis time and computational savings. The main problem that arose during the investigation was the limitation in terms of the size of the mesh that allows the software to be generated in its student version. It was possible to verify that the quality of the mesh directly influences the quality of the results.
