This project seeks to perform the preliminary design of an aerodynamic diffuser to be used in a three-dimensional model of a formula-type vehicle, using computational tools. For the development of this project, the state of the art was taken into account regarding Formula SAE racing vehicles, as well as the general literature on aerodynamics in racing vehicles. The development of the design involves three key moments: 1) The development of a theoretical framework, which defines the computational tools to be made and the physical models that these tools use. 2) Definition and optimization of the geometry in two dimensions that will compose the main structure of the diffuser. 3) Definition and optimization of the final geometry, in three dimensions, of the aerodynamic device. The parameters that were used for the optimization of the geometries, both in two and three dimensions, were the input angle and input area ratio.
Aerodynamic improvements in automotive racing can have a significant effect on vehicle performance. Recent developments in Formula SAE (Society of Automotive Engineers) have included the design and implementation of aerodynamic devices such as inverted wings and undertrays to improve performance. In this work the literature of undertray technology is presented and a design of an undertray for the Global Formula Racing car is developed. Computational Fluid Dynamics simulations are used to iterate the design and discover the effect on the downforce developed of various vehicle parameters such as speed, ride height and roll. Predicted performance is then tested using on-track data and statistical analysis is preformed on lap times from a back-to-back comparison to identify the gain of the undertray. The comparison shows a 31% error from predicted to measured downforce, with a statistically significant 1% improvement in lap times.
The first book to summarize the secrets of the rapidly developing field of high-speed vehicle design. From F1 to Indy Car, Drag and Sedan racing, this book provides clear explanations for engineers who want to improve their design skills and enthusiasts who simply want to understand how their favorite race cars go fast. Explains how aerodynamics win races, why downforce is more important than streamlining and drag reduction, designing wings and venturis, plus wind tunnel designs and more.
This Book: Simulation CFD - 1. Today, the most important in race cars, is the corner behavior. To have a car with a very big velocity, is easy, but the same car in corner, normally not will be the fastest. That is: the main goal is analyzing together the vibrations of suspension, the tires and the aerodynamic. Three tools very importants to improve the grip and so, the velocity and behavior in corner. All this knowledge, available chapter by chapter and book by book. The best book you can find anywhere in the world. All the specialized information.
