The objective of this thesis is to shift the focus towards the precise positioning of the wheels concerning the rotational airflow within a wind tunnel. Previous studies and research have revealed the significant influence that wheel positioning exerts on both aerodynamic coefficients and emissions. To investigate this impact, two distinct methodologies will be employed in an attempt to establish the most robust correlation between real-world observations and virtual simulations. In today’s computing landscape, the available resources enable automotive companies to achieve a strong correlation between numerical Computational Fluid Dynamics (CFD) simulations and wind tunnel experiments. CFD simulations, in comparison to wind tunnel tests, offer cost-effectiveness and flexibility, allowing the examination of different models without the need for constant prototype changes, along with the exploration of various flow field attributes.
