Project Title

Optimization of Vehicle Interior Structure for Drag Reduction

Certificate(s): Engineering Physics, Robotics and Intelligent Systems

I worked in the fluid dynamics lab where my primary focus was researching, designing and testing car designs in order to reduce drag. I first conducted a literature review on existing and theoretical design features, including passive structural changes to the car design and active pump systems. I then worked with the industry-standard fluid-dynamics software Fluent to simulate and test flows around different car designs. Since the Smits Lab is primarily an experimental fluids lab, my testing with Fluent gave the lab valuable experience in the use of computational fluids software. Not only was my team able to create an exterior vehicle design that resulted in promising drag reduction, I also learned a lot about the iterative design process that research labs use to create new and exciting technologies.
