Local thermal non-equilibrium (LTNE) model for developed flow in porous media with spatially-varying Biot number

International Journal of Heat and Mass Transfer, 2021
Abstract The local thermal non-equilibrium (LTNE) model has been extensively used to model convective heat transfer in porous media. Most of the past LTNE-based models account for thermal interactions between fluid and solid phases in the form of a constant Biot number (Bi). This work presents a local thermal non-equilibrium model for fully developed
