This paper presents contamination simulation results of a 2004 Chevrolet Malibu Maxx with different morphed rear declination angles geometry to understand that effect on the vehicle contamination. Computational fluid dynamics highly-resolved time accurate simulations were performed using a commercial Lattice-Boltzmann solver, to compare the rear end contamination with five different rear declination angles. Aerodynamics simulations were also performed and presented good correlation with theoretical data. The contamination results were compared with aerodynamics simulation results in order to find a trend between the two areas for different declination angles.
