This study investigates the role of constriction angle, particle Reynolds number, particle concentration, particle-to constriction size ratio, and constriction smoothness in clogging behavior within semidilute suspensions. A coupled CFD-DEM approach was used to simulate particle transport through a constricted channel, and a discrete stochastic model was developed to describe the statistical nature of clogging events. The model characterizes clogging through the average number of particles, or escapees, that pass through a constriction before a stable arch forms. Results show that the number of escapees decreases with increasing constriction angle and particle concentration, while remaining largely unaffected by injection flow rate within the Stokes regime. The number of particles forming stable arches increases in discrete steps, closely matching integer values of the particle-to-constriction size ratio. Sharper constrictions were observed to promote more frequent and stable clogging compared to smoother geometries. The stochastic model accurately captures these trends, demonstrating its predictive capability across various conditions.} } @article{proudman_pearson_1957, title={Expansions at small Reynolds numbers for the flow past a sphere and a circular cylinder}, volume={2}, DOI={10.1017 S0022112057000105}, number={3}, journal={Journal of Fluid Mechanics}, author={Proudman, Ian and Pearson, J.

Résumé Les auteurs emploient les coordonnées bipolaires pour déterminer le mouvement résultant de deux sphères identiques et homogènes libres, dans un fluide illimité, avec un faible nombre de Reynolds. Des valeurs numériques exactes, sont obtenues pour des vitesses linéaires et angulaires des sphères, en fonction de leur séparation relative et de l'orientation de la ligne des centres par rapport à la direction de la pesanteur. Une comparaison avec les résultats expérimentaux déjà publiés montre que ceux-ci sont en accord avec la théorie et plus spécialement lorsqu'on tient compte des effets de paroi. Zusammenfassung Zur Bestimmung der Endabsetzbewegung zweier identischer, homogener, ungehemmter Kugeln in einer unbegrenzten Flüssigkeit bei niedrigen Reynoldsschen Zahlen werden Bipolarkoordinaten verwendet. Für die Linear- und Winkelgeschwindigkeiten der Kugeln, in Abhängigkeit von ihrer gegenseitigen Trennung und der Ausrichtung ihrer Mittellinien in Bezug auf die Richtung der Schwerkraft, werden genaue zahlenmässige Werte erhalten. Ein Vergleich mit veröffentlichten Daten zeigt gute Überienstimmung, besonders wenn man die Wandeffekte in Betracht zieht.} } @book{krueger2017lbm, abstract = { A textbook that is strong on basics but also includes in-depth descriptions of the latest applications of LBM Thorough chapter summaries, example codes, and an FAQ make this book suitable as both textbook and handbook for practitioners The book webpage gives the full code corresponding to the examples presented in the text}, added-at = {2023-05-15T08:32:39.000+0200}, address = {Cham}, author = {Krüger, Timm and Kusumaatmaja, Halim and Kuzmin, Alexandr and Shardt, Orest and Silva, Goncalo and Viggen, Erlend Magnus}, biburl = {https://www.bibsonomy.org/bibtex/25bef572509fccea3046f021b802a8e80/gdmcbain}, description = {The Lattice Boltzmann Method: Principles and Practice | SpringerLink}, doi = {10.1007/978-3-319-44649-3}, edition = {First}, interhash = {fcc668c7b88b73034d2ef9949bd6eaef}, intrahash = {5bef572509fccea3046f021b802a8e80}, isbn = {978-3-319-83103-9}, keywords = {76-02-fluid-mechanics-research-exposition 76m28-particle-methods-and-lattice-gas-methods-in-fluid-mechanics}, publisher = {Springer}, series = {Graduate Texts in Physics}, timestamp = {2025-08-20T05:09:47.000+0200}, title = {The Lattice Boltzmann Method}, url = {https://link.springer.com/book/10.1007/978-3-319-44649-3}, year = 2017 } @article{KRAUSE2017HLBM, title = {Particle flow simulations with homogenised lattice Boltzmann methods}, journal = {Particuology}, volume = {34}, pages = {1-13}, year = {2017}, issn = {1674-2001}, doi = {https://doi.org/10.1016/j.partic.2016.11.001}, url = {https://www.sciencedirect.com/science/article/pii/S167420011730041X}, author = {Mathias J.

Comparisons of exemplifying simulations to results in the literature validate the approach as well as the convergence analysis. Pressure fluctuations occurring in Ladd’s approach are greatly reduced. In comparison with the immersed boundary method, this approach does not require cost intensive interpolations. The parallel efficiency of LBM is retained. An intrinsic momentum transfer is observed during particle–particle collisions. To demonstrate the capabilities of the approach, sedimentation of particles of several shapes is simulated despite omitting an explicit particle collision model.} } @article{Peskin_2002, title={The immersed boundary method}, volume={11}, DOI={10.1017/S0962492902000077}, journal={Acta Numerica}, author={Peskin, Charles S.}, year={2002}, pages={479–517}} @article{MAYA2024, title = {Particulate transport in porous media at pore-scale.

In this work, the unresolved-resolved four-way coupling CFD-DEM (Computational Fluid Dynamics - Discrete Element Method) proposed in Part 1 is coupled with colloidal forces (long-range interactions) to model the transport of charged particles and retention by aggregation at the pore-scale. The model includes hydro-mechanical interactions (e.g. collision, drag, buoyancy, gravity) and electrochemical interactions (e.g. Van der Waals attraction, electrostatic double layer repulsion) between the particles, the fluid, and the porous formation. An adhesive contact force based on the Johnson-Kendall-Roberts theory allows for realistic particle adhesion on the walls. The model robustness is verified using reference semi-analytical solutions of the particle dynamics including long-range interactions. Finally, our CFD-DEM for particulate transport including DLVO and JKR adhesive contact forces is used to investigate the effect of fluid salinity on pore-clogging and permeability reduction. Importantly and unlike other approaches, our CFD-DEM model is not constrained by the size of the particle relative to the cell size. Our pore-scale model offers new possibilities to explore the impact of various parameters including particle size distribution, particle concentration, flow rates, and pore geometry structure on the particulate transport and retention in porous media.} }
