Print version Email story Tweet story
Application At the recent Mid-America Trucking Show, truck manufacturers Kenworth and International both unveiled new designs developed through the use of CFD. International claims a nine percent improvement in fuel economy as a result of its new aerodynamic shape.
The aerodynamic design dramatically reduces wind resistance, turning in profit-boosting fuel-efficiency performance. Key test applications used to achieve the design were Computational Fluid Dynamics, a computerized application used to optimize design in the early stages of the process, and 1/8 scale wind tunnel testing for basic shape development.
