Paper (04/2023): Congratulations to Honghui for publishing a paper titled "Modeling density-driven flow in porous media by physics-informed neural networks for CO2 sequestration" in Computers and Geotechnics. In collaboration with the UIUC's team, this study aims at exploring the application of deep learning approach in predicting the flow and transport behavior during CO2 injection, with providing a detailed comparison to the classic FEM numerical solver. More details can be found in: https://authors.elsevier.com/a/1gsEh,63b-0Miq.
