Aerodynamic Design And Analysis Of A Modified 2006 Mazda Miata, William N. Recher
Aerodynamic Design And Analysis Of A Modified 2006 Mazda Miata, William N. Recher
Honors College Theses
Aerodynamic forces developed by automobiles have destabilizing effects at high speed. These forces tend to skew toward a vehicle’s rear which can present safety concerns, especially for rear-wheel-drive automobiles like the Mazda Miata. To address oversteer and high-speed instability, a vehicle’s design can be tailored to bring about aerodynamic balance and improve traction. LiDAR was used to bring the physical automobile into the digital space. Then, a splitter and diffuser were added to reduce the magnitude of the destabilizing forces. Next, the size and shape of the rear-wing required to balance the vehicle was calculated using a combination of parameters …
Design And Validation Of An Aerodynamic System For A Formula Sae® Vehicle Using Vehicle Dynamic Simulation And Experimentation, Evan S. Cole
Design And Validation Of An Aerodynamic System For A Formula Sae® Vehicle Using Vehicle Dynamic Simulation And Experimentation, Evan S. Cole
Graduate Theses, Dissertations, and Problem Reports
This thesis presents the design, simulation, and experimental validation for the aerodynamic system for a Formula SAE® vehicle. The Society of Automotive Engineers ® (SAE) hosts a collegiate competition annually called Formula SAE® where students design, fabricate, and test a small “formula style” vehicle. The vehicle performs in relatively slow maneuvers, around different courses and tests to evaluate the vehicle’s overall performance. Over the years, collegiate teams have put significant research into the design and manufacturing of the aerodynamics of these vehicles. In order to justify this undertaking for future teams at West Virginia University’s Formula SAE® program, a comprehensive …
Sedan Performance/Economy Rear Diffuser, Jacob Boucher Koris
Sedan Performance/Economy Rear Diffuser, Jacob Boucher Koris
Thinking Matters Symposium
This project consists of designing in SolidWorks a model of the performance/fuel economy diffuser. The design is modeled with an Ahmed body (recommended shape for CFD testing vehicles) and the diffuser will be applied to the bottom of the rear bumper of the car. After this is done the model will be imported into ANSYS for CFD testing. Testing entails importing the model, then creating a mesh around the model, and then setting up the program to run analysis for calculating the coefficient of drag. Then building this SolidWorks model as a full working prototype for actual road-testing purposes. With …
Cfd Study Of Aerodynamic Drag Reduction Tool Of A Generic Sports Utility Vehicle (Suv), Samira Ishrat Jahan
Cfd Study Of Aerodynamic Drag Reduction Tool Of A Generic Sports Utility Vehicle (Suv), Samira Ishrat Jahan
Masters Theses
The Sports Utility Vehicle (SUV) has been a popular automobile choice in North America for over 50 years due to its seating and hauling versatility and good towing capacity. This widespread popularity has resulted in manufacturers pushing for increased horsepower and cabin size. Unfortunately, the limiting factor has been fuel economy which is governed by the vehicle aerodynamics. A reduction in aerodynamic drag can result in better fuel economy. The goal of this study is to reduce the aerodynamic drag of a generic SUV and the efficient application of drag reduction devices to control flow separation. An initial study has …
An Experimental Study On Drag Reduction Of Aftermarket Additions On An Suv, Christiana L. Katsoulos
An Experimental Study On Drag Reduction Of Aftermarket Additions On An Suv, Christiana L. Katsoulos
Senior Honors Projects, 2010-2019
Over recent years, the awareness of climate change has become more prevalent worldwide and one major contributor to global warming has been the use of transportation. Vehicles contribute to global warming by releasing petroleum based emissions such as significant amounts of carbon dioxide and numerous other harmful environmental pollutants. SUVs contribute to the emissions problem more so than sedans, since they have lower gas mileage and need more gasoline regularly. The main functionality of sport utility vehicles, or SUVs, includes hauling or off-roading and fuel efficiency is not always the focus in the design process. However, aerodynamic enhancements could improve …
External Aerodynamics Of Heavy Ground Vehicles: Computations And Wind Tunnel Testing, Ilhan Bayraktar
External Aerodynamics Of Heavy Ground Vehicles: Computations And Wind Tunnel Testing, Ilhan Bayraktar
Mechanical & Aerospace Engineering Theses & Dissertations
Aerodynamic characteristics of a ground vehicle affect vehicle operation in many ways. Aerodynamic drag, lift and side forces have influence on fuel efficiency, vehicle top speed and acceleration performance. In addition, engine cooling, air conditioning, wind noise, visibility, stability and crosswind sensitivity are some other tasks for vehicle aerodynamics. All of these areas benefit from drag reduction and changing the lift force in favor of the operating conditions. This can be achieved by optimization of external body geometry and flow modification devices. Considering the latter, a thorough understanding of the airflow is a prerequisite.
The present study aims to simulate …
