摘要：	The objective of this report is: (1) provide guidance to industry in the reduction of aerodynamic drag of heavy truck vehicles; and (2) establish a database of experimental, computational, and conceptual design information, and demonstrate potential of new drag-reduction devices. The approaches used were: (1) develop and demonstrate the ability to simulate and analyze aerodynamic flow around heavy truck vehicles using existing and advanced computational fluid dynamics (CFD) tools; (2) through an extensive experimental effort, generate an experimental data base for code validation; (3) using experimental data base, validate computations; (4) provide industry with design guidance and insight into flow phenomena from experiments and computations; and (5) investigate aero devices (e.g., base flaps, tractor-trailer gap stabilizer, underbody skirts and wedges, blowing and acoustic devices), provide industry with conceptual designs of drag reducing devices, and demonstrate the full-scale fuel economy potential of these devices.
