Title: Quarterly Report (Reporting Period January 15, 2003 through April 15, 2003)

Technical Report ·

Summaries of the activities and accomplishments during this second quarter reporting period for each of the consortium participants are given. Some of the highlights for this reporting period include: Even without the forcing speaker, the ''Mozart'' device on the GCM geometry provides over 20% reduction in drag at 0 degree yaw and above 25% reductions at higher yaw angles; Experiments and computations guide a conceptual design for reduction of drag due to tractor-trailer gap flow; RANS simulations for the GTS geometry are being finalized for development of clear modeling guidelines with RANS; Simulations on the GCM geometry have begun; and Vortex methods have improved techniques for the treatment of vorticity near surfaces.
