According to the abstract released by the Intellectual Property India: "The invention relates to a unified theoretical and numerical framework for analyzing non-linear heat and mass transfer phenomena in porous media saturated with nanofluids. The framework comprises a porous medium domain module (100) with porous matrix structure (110), nanofluid properties (120), Brownian motion (122), thermophoresis (123), variable properties (130), Darcy-Brinkman-Forchheimer flow dynamics (140), and boundary conditions (150); a transport phenomena module (200) with heat transfer (210) including Joule heating (211), mass transfer (220), and thermal-diffusive coupling (230); a numerical solution module (300) with coupled PDEs (310), discretization (320), iterative solver (330), and convergence analysis (340); and an output/optimization module (400) generating temperature distribution (410), concentration field (420), transfer enhancement metrics (430), and optimization parameters (440). The present invention ensures precise prediction of temperature distribution, nanoparticle concentration fields, and mass transfer enhancement by providing unified treatment of non-linear thermal diffusion, nanoparticle migration, Darcy-Forchheimer resistance, viscous dissipation, Joule heating, Soret effects, chemical reactions, and internal heat generation within a single predictive framework, enabling optimization of thermal management systems, energy storage devices, catalytic reactors, and engineered porous materials."
