Parolin Aero Package CFD Analysis

This project focused on analyzing the latest Parolin kart aero package using detailed CFD airflow simulations. The study compared the new bodywork directly against the previous generation under identical testing conditions to evaluate improvements in airflow management, drag reduction, and downforce generation.

The analysis examined the redesigned front bumper, front panel, and sidepods. Results showed that the new bumper design improved airflow attachment and reduced separation compared to the older version, helping increase aerodynamic efficiency at the front of the kart. The sidepods continued to effectively direct airflow around the rear wheels, minimizing turbulence.

The most significant changes were observed in the front panel design. The new inlet and outlet system redirected airflow away from the driver, reducing high-pressure zones around the chest and helmet area. This significantly improved airflow control and lowered aerodynamic drag. However, the updated front panel also introduced small lift regions, slightly reducing overall downforce compared to the previous generation.

Simulation data showed the kart achieved a drag coefficient of 0.57 and a lift coefficient of -0.14. At 72 km/h, the kart generated approximately 2.2 kg of downforce while experiencing 85N of aerodynamic drag.

Overall, the project demonstrated that manufacturers using this aero package focused primarily on drag reduction and cleaner airflow management, even at the cost of slightly lower downforce.
