Abstract

Motorsport's competitive demands drive innovation, such as optimizing fuel tank performance by reducing sloshing and ensuring efficient fuel extraction. This study explores a meshless CFD approach using Moving Particle Simulation (MPS) to streamline workflows and reduce computational costs compared to traditional finite volume method (FVM) CFD.

Key findings include:

• Efficiency Gains: MPS enables faster simulations with reduced hardware needs, allowing Dallara Automobili to analyze sloshing over more tracks in less time.
• Optimal Particle Size: A 3.5mm particle size strikes a balance between accuracy and computational efficiency.
• Teflon Sphere Innovation: Adding solid spheres reduces sloshing (14% in x, 8% in y, 17% in z directions) without affecting fuel flow, offering performance advantages in partially filled tanks.

This approach provides actionable insights for enhancing racing fuel tank design, advancing precision and efficiency in motorsport engineering.
