Fuel cost reduction by improving aerodynamics of a semi trailer

Semi trailer manufacturer H.W. van der Peet & Zn aims for low total cost of ownership for its end users. By improving the aerodynamics of a truck with a semi trailer, the fuel costs are reduced. The aim of this research is how to reduce the aerodynamic drag of the “Kolibri” semi trailer (a belt unloader), without compromising production costs and load capacity, and with the new design still satisfying legal demands. Using computational fluid dynamics, the aerodynamic drag of the semi trailer has been examined and a new design has been developed with reduced drag. Coast down tests have been carried out to validate the CFD investigation. Rounding of the front end of the semi trailer and tapering of the rear end resulted in the biggest improvement. Side skirts added to drag reduction as well. Fuel consumption tests were carried out, using the final production version of the semi trailer. With an empty vehicle, the fuel consumption was reduced by 6.5%.
