CFD Modeling of Porous Media Flow
Research Guide
What is CFD Modeling of Porous Media Flow?
CFD Modeling of Porous Media Flow uses volume-averaged and particle-resolved computational fluid dynamics to simulate fluid flow, heat, and mass transfer in porous structures at homogenized or resolved scales.
This subtopic encompasses porous zone models, lattice Boltzmann methods, and direct numerical simulations validated against micro-CT geometries. Key works include multiphase lattice Boltzmann simulations (Liu et al., 2015, 427 citations) and particle-resolved CFD for fixed-bed reactors (Jurtz et al., 2018, 245 citations). Over 1,000 papers address scale separation in heat/mass transfer applications.
Why It Matters
CFD modeling enables virtual prototyping of fixed-bed reactors, improving catalyst design and efficiency (Dixon and Partopour, 2020). In heat exchangers, microarchitected lattices from 3D printing enhance thermal performance (Dixit et al., 2022). Tomography-based simulations characterize reticulate porous ceramics for high-temperature processes (Haussener et al., 2009), reducing experimental costs in solar absorbers and CPU cooling systems.
Key Research Challenges
Scale Separation
Bridging pore-scale and Darcy-scale phenomena requires multi-scale modeling. Liu et al. (2015) highlight lattice Boltzmann for multiphase flows, but validation against micro-CT structures remains computationally intensive. Haussener et al. (2009) use tomography for pore-level accuracy.
Particle-Resolving Accuracy
Direct numerical simulations demand high resolution for packed beds. Jurtz et al. (2018) review CFD advances since Dixon et al. (2006), noting challenges in wall effects and heat transfer. Das et al. (2016) apply DNS to slender reactors with spherical particles.
Multiphase Wettability Effects
Heterogeneous wettability alters relative permeability in two-phase flows. Zhao et al. (2018) employ lattice Boltzmann to quantify impacts. Coupling with heat/mass transfer adds non-equilibrium complexities (Hayes et al., 2008).
