Full-field prediction for engineering-scale three-dimensional aircraft with multigrid-hierarchical learning

Researchers introduce MHLF, a multigrid-hierarchical deep learning framework that accelerates computational fluid dynamics simulations for full-scale 3D aircraft by 3-8x while maintaining high-fidelity accuracy across subsonic, transonic, and supersonic flight regimes. This breakthrough addresses a critical bottleneck in aerospace design by enabling practical full-flow-field prediction for engineering-scale aircraft, moving beyond previous limitations of 2D or simplified models.

Accelerated and data-efficient flow prediction in stirred tanks via physics-informed learning

Researchers demonstrate that physics-informed machine learning can predict fluid flows in industrial stirred tanks with significantly less training data than purely data-driven approaches. The study reveals diminishing returns in accuracy beyond moderate dataset sizes, with physics-based constraints proving most valuable in low-data regimes.

Data-Free PINNs for Compressible Flows: Mitigating Spectral Bias and Gradient Pathologies via Mach-Guided Scaling and Hybrid Convolutions

Researchers developed a data-free Physics-Informed Neural Network (PINN) that can solve compressible flows around circular cylinders at extreme speeds up to Mach 15. The system uses hybrid convolutions and Mach-guided scaling to overcome traditional limitations and successfully captures shock waves without requiring training data.
