Numerical Modeling of Drag Reduction by Bionic Microstructures on High-speed Trains

With the continuous increase in the operating speed of high-speed trains, aerodynamic performance plays an increasingly critical role in energy consumption, operational stability, and passenger comfort. Among various aerodynamic factors, drag has become a key constraint on train efficiency. As train-shape optimization...

A comparative study of preprocessing methods for physics-informed neural networks in fluid mechanics

This study systematically compares PINNs preprocessing methods, with particular focus on three universal approaches (the non-dimensionalization, inner normalization layers, and synergistic normalization method for data and equation), and provides a practical reference for selecting preprocessing methods in different ph...
