Physics-informed neural networks advance solute dispersion simulation

Researchers have developed a novel physics-informed neural network (PINN) framework to simulate solute dispersion in shear flows with reactive walls. This mesh-free approach embeds the governing convection-diffusion equation and Robin boundary conditions into a loss function, allowing for accurate reconstruction of spatiotemporal concentration fields. The PINN framework was validated against a finite-difference benchmark and demonstrated its ability to extract detailed transport diagnostics, such as axial dispersion coefficients and localized uptake fluxes. The study highlights the potential of PINNs as an interpretable tool for analyzing complex reactive transport phenomena in fluid dynamics. AI
