| 6 | Simulating fluid flow in complex porous materials by integrating the governing equations with deep-layered machines显示文摘Fluid flow in heterogeneous porous media arises in many systems,from biological tissues to composite materials,soil,wood,and paper.With advances in instrumentations,high-resolution images of porous media can be obtained and used directly in the simulation of fluid flow.The computations are,however,highly intensive.Although machine learning(ML)algorithms have been used for predicting flow properties of porous media,they lack a rigorous,physics-based foundation and rely on correlations.We introduce an ML approach that incorporates mass conservation and the Navier–Stokes equations in its learning process.By training the algorithm to relatively limited data obtained from the solutions of the equations over a time interval,we show that the approach provides highly accurate predictions for the flow properties of porous media at all other times and spatial locations,while reducing the computation time.We also show that when the network is used for a different porous medium,it again provides very accurate predictions. | Serveh Kamrava Muhammad Sahimi Pejman Tahmasebi | 2021 | npj Computational Materials2021，，1： | 0 |
