New AI framework uses residual attention physics-informed neural networks to improve simulations of complex electrothermal energy systems.

Residual Attention Physics-Informed Neural Network (RA-PINN) framework solves coupled multiphysics problems involving velocity, pressure, electric potential, and temperature fields simultaneously

Addresses key challenges in steady-state simulation including strong nonlinear field coupling, temperature-dependent coefficient variability, and complex interface dynamics

Integrates residual-connected feature propagation and attention-guided channel modulation to capture localized coupling structures and steep gradients

Designed for applications in electrohydrodynamic transport, microfluidic energy harvesters, and electrically driven thermal regulators
