What are the current advancements in machine learning techniques applied to fluid mechanics?5 answersCurrent advancements in machine learning techniques applied to fluid mechanics include enhancing measurement techniques' fidelity, improving experimental design, enabling real-time estimation and control, and addressing missing information in partially observable systems. Researchers are exploring methods like deep learning for simulating fluid dynamics, with physics-driven models minimizing residuals of governing equations and data-driven models providing fast solutions based on observed physical properties. These approaches aim to accelerate iterative solvers, enhance turbulence modeling, and automate traditionally complex tasks like image synthesis and natural language processing. Challenges remain, such as poor extrapolation in data-driven simulators and difficulties in training against turbulent flows, prompting ongoing efforts to enhance these techniques.
How can physics-informed neural networks be useful in computational geomechanics?5 answersPhysics-informed neural networks (PINNs) have shown promise in computational geomechanics. PINNs can adapt to changes in geometry and mesh definitions, allowing for generalization across different shapes. They have been used to simulate fluid flows in complex geometries, such as 3D Y-shaped mixers, resulting in higher accuracy compared to classical neural networks. PINNs have also been applied to solve the partial differential equation governing the thermo-poro-mechanical behavior of shear bands in deep-seated landslides. By training a deep neural network with synthetic data, PINNs can estimate the temperature inside the shear band and forecast the stability of landslides in real-time. PINNs, along with other neural operators like Deep Operator Networks, Fourier neural operators, and graph neural operators, have been used as surrogates in design problems, uncertainty quantification, and autonomous systems in computational mechanics, including geomechanics.

How are physics-informed neural networks used in climate prediction?5 answersPhysics-informed neural networks (PINNs) are used in climate prediction to find solutions and identify parameters of partial differential equations. These networks are flexible and can handle noiseless data or data contaminated by weak Gaussian noise. However, the standard PINN framework breaks down when dealing with non-Gaussian noise. To address this issue, a joint training approach is proposed, where an energy-based model (EBM) is trained to learn the correct noise distribution. This approach improves the performance of PINNs in the presence of non-Gaussian noise. In addition, deep learning combined with causal discovery is used to remove spurious correlations and optimize the neural network algorithm in climate simulations. This approach helps retain convection-related properties of high-resolution climate models and leads to stable and more accurate climate simulations.
What are the recent trends in physics informed neural networks?5 answersPhysics-informed neural networks (PINNs) have recently emerged as a promising approach for solving partial differential equations (PDEs) by integrating physical models with observational data. Recent trends in PINNs include the development of new network architectures and training algorithms to overcome the limitations of training PINNs for multi-dimensional PDEs and complex solution functions. One such method is the separable PINN (SPINN) which reduces the number of network propagations in multi-dimensional PDEs and enables a large number of collocation points on a single GPU. Another trend is the use of incremental PINNs (iPINNs) which can learn multiple tasks sequentially without additional parameters and achieve lower prediction error compared to regular PINNs. Additionally, there have been advancements in understanding the training dynamics of PINNs and developing adaptive training strategies using Neural Tangent Kernel theory. These trends aim to enhance the trainability, generalization performance, and efficiency of PINNs in solving PDEs.
How can we use physics-guided deep learning to improve production forecasting and diagnostics in unconventional wells?4 answersPhysics-guided deep learning (PGDL) models can improve production forecasting and diagnostics in unconventional wells. These models incorporate physical flow functions into neural networks, allowing them to capture the general production behavior of unconventional wells. By embedding physics into the models, they can provide predictions beyond available data and adhere to the general production trends. However, the performance of PGDL models depends on the relevance of the embedded physics, and residual prediction errors may occur if the collected data do not match the embedded model sufficiently. To compensate for these errors, residual learning is used, where an auxiliary neural network learns the relationship between input parameters and prediction residuals. This approach increases the prediction accuracy of the PGDL models. Overall, PGDL models offer a physics-informed approach to production forecasting and diagnostics in unconventional wells, combining the strengths of physics-based models and machine learning.
