Tractor Trailer Aerodynamics in SolidWorks Flow Simulation

As time progresses and fuel prices increase, you might have noticed some changes to the tractor trailers you see on the highway. Fairings on tractors have been common for quite a while; however, side skirts and extended “tails” on the trailers are relatively new additions.

To satisfy my curiosity on the effectiveness of these devices, I’ve performed a virtual experiment using Flow Simulation. Watch the quick video below to see the results of the test.
