Energy-Conserving Neural Network Closure Model for Long-Time Accurate and Stable LES
PositiveArtificial Intelligence
- A novel skew-symmetric neural architecture has been developed as a closure model for large eddy simulations (LES), addressing the instabilities and physical inconsistencies often seen in machine learning-based models. This model ensures stability while adhering to essential conservation laws of mass, momentum, and energy, and has been tested against conventional data-driven closures and the Smagorinsky model.
- The introduction of this energy-conserving model is significant as it enhances the accuracy and stability of simulations in fluid dynamics, which are crucial for various applications in engineering and environmental sciences. By maintaining physical conservation laws, the model promises to improve predictive capabilities in turbulent flow scenarios.
- This advancement reflects a broader trend in artificial intelligence where researchers are increasingly focusing on integrating physical principles into machine learning models. The ongoing exploration of multi-fidelity neural emulators and adaptive sampling techniques highlights the importance of balancing data-driven approaches with established scientific theories to enhance predictive performance across diverse fields.
