Abstract:

Motivated by autonomous and connected vehicle technology, truck platooning has significant economic benefits on the freight transportation industry. Lower average fuel consumption can be achieved due to the reduced air-drag force experienced by the platoon during operation. This report presents the procedure and results of computational fluid dynamics (CFD) analysis and aims to evaluate the stationary air drag on platooned freight trucks. CFD simulation is performed on paired truck models using the Ansys Fluent software to quantify the effect of positioning on drag force. A prediction model is proposed to evaluate the average air drag on platoons of various sizes and spatial configurations. The results of this study showed the loss of air-drag reduction in platooning when trucks are separated and misaligned and suggested the platoon size needed to achieve maximum drag reduction.
