The air-deflector and the drag: A case study of low drag cab styling for a heavy truck

This paper has investigated the cab styling of heavy-duty truck with a low air drag based on aerodynamics and aesthetics. It focuses on the relationship of air-deflector, trailer and drag through an example of air-deflector styling. The parameters, the angle of air-deflector and the height of trailer, are specifically discussed here. The gap between cab and trailer is fixed. A lower drag cab is presented here by applying the CFD analysis result.
