Computational Fluid Dynamics

Expanding the use of Aircraft Technology

CFD: Jet Image

In the aircraft industry, Computational Fluid Dynamics can take a 747 and predict its physics to within 1 percent accuracy, providing critical insight into its speed, maneuverability and fuel usage.

AVR uses the same advanced technology to work with any object moving through a fluid or gas or any object that has fluid moving through it. Using a complex mathematical process that applies aerodynamics to the 3D image of the product, you can test against 100+ million points or higher. Advanced Vehicle Research can simulate racecars in drafting configurations, a submarine in water, a fisherman's spinner bait and modifications of each — all to see the differences in performance.

Test... ANALYZE... Adjust... Repeat...

Computational Fluid Dynamics provides you with a wealth of information whose value is realized only when properly understood and applied. AVR's expertise – the combined knowledge of the nation’s top aerodynamic engineers and aircraft developers – is unmatched.

By funneling results and information back and forth between Computational Fluid Dynamics and Design, AVR takes results from the virtual world and transforms them into results in the real world. AVR will collaborate with your engineers to design and optimize your product and help you understand exactly what is happening with the aerodynamics. Using AVR provides a means to test things that could never be tested in a wind tunnel and will give a more accurate results for those objects that can be tested.

Example:

How Important is an Aero Advantage in NASCAR?

Simulations of typical NASCAR cars on 1.5 mile ovals show:
  • An improvement in down force coefficient of 0.1 is worth 1.8 mph increase in lap speed
  • It would take 60 to 70 HP to generate this kind of speed improvement
  • A 5% reduction in drag is worth 0.5 mph - equivalent to 25 hp increase
  • A 1.8 + mph increase in qualifying speed is worth 15 places (20th to 5th at the analyzed race at Atlanta Motor Speedway)
The impact of Aero on super speedways like Daytona and Talladega (with restricted engines) is larger:
  • Power is way down and hard to come by
  • Cars are full throttle in corners
  • Drag reduction is essential for competitiveness
