Abstract EN
Dispersion of vehicle exhaust gas is a primary source of air pollution in urban areas.
Thus, it has become an important subject in the automotive field.
This paper consists of two parts.
First, the fastback MIRA model was selected as study object and a standard κ-ε two-equation turbulence model was used.
The simulation results were compared and analyzed with experimental data.
The feasibility of the turbulence model and grid strategy was then verified, and the results were used in the next research step.
Second, we used propane as tracer gas while ignoring the effect of the vehicle wake field force on this gas.
The tracer gas diffusion in the wake flow field was then simulated through fastback, notchback, and square-back MIRA models.
This study focuses on analyzing the characteristics of wake field diffusion effects, particularly in the near wake of a vehicle.
