Researchers have developed eight new surrogate models to predict fluid flow in porous media, aiming to reduce the computational expense of traditional high-fidelity numerical models. Four of these are reduced-order models (ROMs) utilizing a neural network for compression and another for prediction. The other four are novel grid-size-invariant single neural networks capable of inferring on domains larger than those used during training. Comparative analysis showed that the UNet++ architecture outperformed UNet, and the grid-size-invariant approach proved effective in reducing memory consumption and correlating predicted values with ground truth.
