摘要：Understanding ground vehicles aerodynamics allows us to optimize the operation of a wide spectrum of road vehicles, that ranges from road passenger transport (cars, buses, trains) to road comercial transport (trucks and trains). Within the first group, the so called “double-deck buses” have awakened an increasing interest, given their extensive utilization in our country. According to this, a series of investigations were initiated at the CIMEC (Centro Internacional de Métodos Computacionales en Ingeniería) focussing in the modeling and the understanding of the aerodynamic characteristics of these large vehicles.
