Caracterización del Flujo y Análisis de Parámetros de Diseño Mediante la Dinámica de Fluidos Computacional para la Construcción de un Túnel de Viento Subsónico

Abstract

This work presents a flow characterization for the design guidance of an open-circuit subsonic wind tunnel with a measured working cross-sectional area of 600 mm x 600 mm at the Universidad Tecnologica del Uruguay. The turbulence intensity in the test section and vorticity in the diffuser are analysed using Computational Fluid Dynamics with a k-w SST turbulence models. It is presumed that the analysis will provide relevant information to improve the wind tunnel design, with emphasis on optimizing the design process of the different sections of this equipment to be constructed by the institution. The expected results include a better understanding of flow patterns and identification of critical points that require adjustments to achieve low turbulence intensity and vorticity, as well as providing fundamental information about the cone and diffuser geometry, as the apparatus is intended to be built. Additionally, the study is expected to contribute to the validation of flow in wind tunnels, providing a solid foundation for future aerodynamic studies on this equipment.
