Physics and Data Driven Transformer-Mamba Framework for Flow Field

Researchers Zhuo Zhang, Shun Zou, Canqun Yang and Xi Yang introduced the Transformer-Mamba for Flow Field (TM4FF) framework, a physics-constrained operator learning model for computational fluid dynamics, in a paper posted to arXiv as 2609.29087v1. TM4FF combines a Residual Wavelet Mamba (RWM) layer for feature denoising, a Transformer-based attention mechanism for feature fusion, and a physics-informed loss using Fourier derivatives to enforce the Navier-Stokes equations. Across four CFD datasets, the framework achieved high accuracy and robust generalization across varying flow conditions, addressing generalization, noise robustness and physical consistency limits the authors attribute to methods such as PINNs and FNOs.

We introduce the Transformer https://www.machinebrief.com/glossary/transformer -Mamba for Flow Field TM4FF framework, a physics-constrained operator learning model with three key innovations: a Residual Wavelet Mamba RWM layer for feature denoising, a Transformer-based attention mechanism https://www.machinebrief.com/glossary/attention-mechanism for enhanced feature fusion, and a physics-informed loss using Fourier derivatives to enforce the Navier-Stokes equations. Experiments on four CFD datasets show TM4FF achieves high accuracy and robust generalization across varying flow conditions. Get AI news in your inbox Daily digest of what matters in AI.
