Analysis of Variants Within the Porous Media Transport Models

摘要: An investigation of variants within the porous media transport models is presented in this work. Four major categories modeling processes through media, namely constant porosity, variable thermal dispersion, and local non-equilibrium, are analyzed detail. The main objective current study to compare these variances for each four establish conditions leading convergence or divergence among different models. To analyze effects models, a systematic reduction sensitivity aspects presented. Darcy number, inertia parameter, Reynolds particle diameter, fluid-to-solid conductivity ratio on areas analyzed. For some cases have negligible effect results while variations can become significant. In general, more pronounced velocity field substantially smaller temperature Nusselt number distribution
