Physics-informed machine learning of redox flow battery based on a two-dimensional unit cell model

no code implementations31 May 2023 Wenqian Chen, Yucheng Fu, Panos Stinis

To solve the 2D model with the PINN approach, a composite neural network is employed to approximate species concentration and potentials; the input and output are normalized according to prior knowledge of the battery system; the governing equations and boundary conditions are first scaled to an order of magnitude around 1, and then further balanced with a self-weighting method.

Enhanced physics-constrained deep neural networks for modeling vanadium redox flow battery

no code implementations3 Mar 2022 Qizhi He, Yucheng Fu, Panos Stinis, Alexandre Tartakovsky

To improve the accuracy of voltage prediction at extreme ranges, we introduce a second (enhanced) DNN to mitigate the prediction errors carried from the 0D model itself and call the resulting approach enhanced PCDNN (ePCDNN).

Latent Space Simulation for Carbon Capture Design Optimization

1 code implementation22 Dec 2021 Brian Bartoldson, Rui Wang, Yucheng Fu, David Widemann, Sam Nguyen, Jie Bao, Zhijie Xu, Brenda Ng

This raises the possibility of a fast, accurate replacement for a CFD simulator and therefore efficient approximation of the IAs required by CCS design optimization.
