• Numerical simulation of convective heat transfer between air flow and ceramic foams to optimise volumetric solar air receiver performances (2011, background): “There are several tortuosity–porosity relations in the literature [46–49].”
• Numerical simulation of cementitious materials degradation under external sulfate attack (2010, background): “Diffusion of an ion through a saturated porous material under isothermal conditions is modeled by taking into account diffusion of ions under a concentration gradient as well as under a chemical activity gradient, assuming diffusion under electrical potential is negligible [7,31,32].”
• Validity of the Bruggeman relation for porous electrodes (2013, background): “Geometrically, tortuosity is commonly defined as the ratio of the average ion diffusion length to the electrode thickness, τ = l/L, where l is the ion diffusion length across the electrode and L is the electrode thickness [24].”
• Tortuosity of porous media: Image analysis and physical simulation (2021, neutral): “Indeed, the tortuosity values calculated from various phenomenological models often differ greatly from experimental measurements or numerical simulation results and are even incorrect in some cases (Shen and Chen, 2007; Matyka et al., 2008; Lanfrey et al., 2010; Tjaden et al., 2018).”
• 3D numerical simulation of flow and conjugate heat transfer through a pore scale model of high porosity open cell metal foam (2010, background): “The tortuosity of a porous medium is defined as the ratio of the total winding path length available for flow in the representative unit cell of the porous medium to the basic streamwise length scale ([28]):”
• Old and New Approaches Predicting the Diffusion in Porous Media (2018, background): “Possible choices for the parameters are discussed in Shen and Chen (2007).”
