Numerical simulation of the transient aerodynamic phenomena induced by passing manoeuvres

Abstract : Several three-dimensional Unsteady Reynolds-Averaged Navier-Stokes (URANS) simulations of the passing generic vehicles (Ahmed bodies) are presented. The relative motion of vehicles was obtained using a combination of deforming and sliding computational grids. Two different vehicle bodies were studied having an angle of the rear end slanted surface of 30 • and 0 •. Several different relative velocities and transversal distances between vehicles were studied. Aerodynamic influence of the passage on both the overtaken and the overtaking vehicles was studied. The results of the simulations were found to agree well with the existing experimental data.
