It is our pleasure to present these proceedings for "The Aerodynamics of
Heavy Vehicles II: Trucks, Buses and Trains" International Conference
held in Lake - hoe, California, August 26-31, 2007 by Engineering
Conferences International (ECI). Brought together were the world's
leading scientists and engineers from industry, universities, and
research laboratories, including truck and high-speed train
manufacturers and operators. All were gathered to discuss computer simu-
tion and experimental techniques to be applied for the design of the
more efficient trucks, buses and high-speed trains required in future
years. This was the second conference in the series. The focus of the
first conference in 2002 was the interplay between computations and
experiment in minimizing ae- dynamic drag. The present proceedings, from
the 2007 conference, address the development and application of advanced
aerodynamic simulation and experim- tal methods for state-of-the-art
analysis and design, as well as the development of new ideas and trends
holding promise for the coming 10-year time span. Also - cluded, are
studies of heavy vehicle aerodynamic tractor and trailer add-on - vices,
studies of schemes to delay undesirable flow separation, and studies
of - derhood thermal management.
