Análisis aerodinámico de un flujo de aire constante alrededor de un Renault Logan por medio del programa de mecánica de fluidos Ansys-Fluent.

Abstract

The project covers a comprehensive review of fundamental topics in fluid mechanics. Among them, aspects such as laminar and turbulent flow, streamlines, vorticity, aerodynamic coefficients, and efficiency are highlighted. In addition, important properties of fluids, such as density, pressure, inertial and viscous forces, are thoroughly explored. These concepts are crucial for understanding the data obtained through the Ansys Student tool and enable a deeper analysis of fluid behavior in various applications and systems. Overall, the project provides a solid foundation for the study and application of fluid mechanics in various engineering and scientific fields.

Secondly, the 3D modeling of the Dacia Logan's body is carried out, both with and without aerodynamic additives, using the SolidWorks tool. Subsequently, both models are loaded into the Ansys CFD tool, where meshing and initial boundary conditions are established. Numerical approximation and data processing for visualization are performed. Finally, data from the processing are extracted to make comparisons between the body with and without aerodynamic additives, using the reviewed concepts of fluid properties and fluid mechanics. These comparisons specifically focus on efficiency and consumption, as these are the main purposes of the employed aerodynamic additives. When analyzing the results, the aim is to understand how the additives affect the airflow around the vehicle.
