How Much Do Mudflaps Increase Your Fuel Consumption?

Should you remove your mudflaps to reduce fuel consumption? To find out, we simulated the Toyota Hilux with mud guards and without to see how the drag coefficient, and fuel consumption were affected. Using identical simulation conditions, we compare at different: Velocity, pressure, and streamline behavior Where lift is generated Where drag is produced Where the noise is produced Want your own car simulated? I also offer custom CFD simulations for vehicles and aerodynamic concepts. 👉 https://premieraerodynamics.com/Simulate-Your-Own-Car/ Want to learn how to do simulations like this? These simulations were run using OpenFOAM. If you want to learn the fundamentals of OpenFOAM — and how to apply them to real engineering problems — check out my course here: 👉 https://premieraerodynamics.com/Courses/ Want to understand vehicle aerodynamics properly? I also teach: Automotive Aerodynamics — understand lift, drag, and wake behavior RC Aircraft Design — applied aerodynamics from the ground up 👉 https://premieraerodynamics.com/Automotive-Aerodynamics/ 👉 https://premieraerodynamics.com/RC-Airplane-Course/ Want free stickers? https://premieraerodynamics.com/Free-Stickers/ pictures used: https://en.wikipedia.org/wiki/Toyota_Hilux#/media/File:Toyota_Hilux_SRV_2.8_TD_2023_(54286671377)_(cropped).jpg, https://creativecommons.org/licenses/by-sa/2.0 Details about simulation: MRFs for the wheels, model is as accurate as we can get. Meant for general entertainment.
