Generative AI Driven Aerodynamic Shape Optimization: A Neural Network-Based Framework for Enhancing Performance and Efficiency
Abstract
Aerodynamic shape optimization plays a crucial role in enhancing the efficiency and performance of air and fluid flow-based systems, particularly in aerospace and automotive industries. Traditional optimization techniques rely on computationally expensive simulations and iterative solvers, which pose significant challenges in terms of time and resource consumption. In this study, we propose a novel Generative AI-driven aerodynamic shape optimization framework that leverages deep neural networks to streamline the optimization process. Our approach integrates generative adversarial networks (GANs) and variational autoencoders (VAEs) to generate and refine aerodynamic shapes with optimal performance metrics. By training the neural network on high-fidelity computational fluid dynamics (CFD) datasets, we enable the model to predict optimal aerodynamic shapes with reduced computational overhead. The proposed framework incorporates physics-informed machine learning techniques, ensuring adherence to fluid dynamics principles while significantly accelerating the optimization process. We demonstrate the effectiveness of our approach by applying it to benchmark aerodynamic cases, including airfoil and automotive body designs, where the AI-driven optimization leads to a substantial reduction in drag and improved lift-to-drag ratios. Comparative analysis against traditional evolutionary algorithms and adjoint-based solvers highlights the superior efficiency and accuracy of our method.…
