Key Papers Explained
"Recommendations for the characterization of porous solids (Technical Report)" (Rouquérol et al., 1994) establishes porous media standards foundational for filtration studies. "Multiphase Flows with Droplets and Particles" (Crowe et al., 2011) builds on this by addressing droplet and particle dynamics in precipitators. "Lattice Boltzmann model for simulating flows with multiple phases and components" (Shan and Chen, 1993) and "Theory of the lattice Boltzmann method: Dispersion, dissipation, isotropy, Galilean invariance, and stability" (Lallemand and Luo, 2000) extend modeling capabilities for electrohydrodynamic flows, while "The lattice Boltzmann equation: theory and applications" (Benzi et al., 1992) offers a broad theoretical framework connecting these advances.
