Abstract

Aerodynamic optimization plays a vital role in achieving sustainability, enhanced vehicle performance, and fuel efficiency in modern automotive design. Conventional methods, such as wind tunnel testing and computational fluid dynamics (CFD), are often time-intensive and resource-demanding, which can slow the design process. This study proposes a machine learning-based framework for dynamic flow line adaptation, enabling efficient real-time aerodynamic optimization for vehicles. By leveraging deep learning techniques, the approach mitigates the challenges associated with traditional methods, achieving notable improvements in computational efficiency and design flexibility. Our findings demonstrate substantial reductions in aerodynamic drag (12%) and computational overhead (15% compared to traditional CFD methods), while maintaining structural integrity within 95% confidence levels. The system achieves 92% prediction accuracy for drag coefficients with an average processing time of just 3.2 seconds per design iteration, facilitating more streamlined and cost-effective vehicle design workflows.
