Aerodynamic drag reduction of heavy vehicles using append devices by CFD analysis
TL;DR: In this article, the effects of adding append devices like deflector and cab vane corner on heavy commercial vehicle drag reduction were investigated, and the results showed that the most effective supplementary part is deflector, and by adding this part, the drag coefficient is decreased considerably at an optimum angle.
