DEM/CFD Simulations of a Pseudo-2D Fluidized Bed: Comparison with Experiments
Autor: Ziad Hamidouche, Yann Dufresne, Jean-Lou Pierson, Rim Brahem, Ghislain Lartigue, Vincent Moureau
Publikováno v: Fluids, Vol 4, Iss 1, p 51 (2019)
The present work investigates the performance of a mesoscopic LaGrangian approach for the prediction of gas–particle flows under the influence of different physical and numerical parameters. To this end, Geldart D particles with 1 mm diameter and d

Hydrodynamic torque on a slender cylinder rotating perpendicularly to its symmetry axis
Autor: Jean-Lou Pierson, Jacques Magnaudet, Mohammed Kharrouba
Publikováno v: Physical Review Fluids
Physical Review Fluids, American Physical Society, 2021, 6 (9), pp.094303. ⟨10.1103/PhysRevFluids.6.094303⟩
International audience; Using fully-resolved simulations, we examine the torque experienced by a finite-length circular cylinder rotating steadily perpendicularly to its symmetry axis. The aspect ratio χ, i.e., the ratio of the length of the cylinde

Bubble Entrapment Condition in Bingham Materials
Autor: Jean-Lou Pierson, Lucas H.P. Deoclecio, Hiranya Deka, Edson J. Soares
Publikováno v: Journal of Non-Newtonian Fluid Mechanics
Journal of Non-Newtonian Fluid Mechanics, Elsevier, 2021, 295, pp.104616. ⟨10.1016/j.jnnfm.2021.104616⟩
International audience; We investigate the entrapment condition of initially spherical and ellipsoidal Newtonian bubbles in viscoplastic materials using direct numerical simulations. For a spherical bubble, the entrapment condition depends on the bal

Flow structure and loads over inclined cylindrical rodlike particles and fibers
Autor: Jean-Lou Pierson, Jacques Magnaudet, Mohammed Kharrouba
Publikováno v: Physical Review Fluids
Physical Review Fluids, American Physical Society, 2021, 6 (4), pp.044308. ⟨10.1103/PhysRevFluids.6.044308⟩
The flow past a fixed finite-length circular cylinder, the axis of which makes a nonzero angle with the incoming stream, is studied through fully-resolved simulations, from creeping-flow conditions to strongly inertial regimes. The investigation focu

Retraction criteria of viscoplastic drops and sheets : long-wave approximations
Autor: Jean-Lou Pierson, Edson J. Soares, Hiranya Deka
Publikováno v: Journal of Non-Newtonian Fluid Mechanics
Journal of Non-Newtonian Fluid Mechanics, Elsevier, 2020, 284, pp.104352. ⟨10.1016/j.jnnfm.2020.104352⟩
International audience; Retraction dynamics of viscous drops and sheets depend on the relative magnitude of the viscous force over the inertia-capillary force. The dynamics are more complicated in the case of viscoplastic drops/sheets because the yie

Revisiting the Taylor-Culick approximation. II. Retraction of a viscous sheet
Autor: Jean-Lou Pierson, Hiranya Deka
Publikováno v: Physical Review Fluids. 5
The retraction of a viscous liquid sheet is studied using direct numerical simulations and long-wave asymptotic models. In the viscous regime, there exists a self-similar solution for the interface and the velocity profiles of a retracting sheet. Thi

Revisiting the Taylor-Culick approximation: Retraction of an axisymmetric filament

Publikováno v: Physical Review Fluids
Physical Review Fluids, American Physical Society, In press, 5 (7), pp.073602. ⟨10.1103/PhysRevFluids.5.073602⟩
International audience; We numerically study the retraction of an axisymmetric viscous filament in a passive surrounding fluid. The analysis focuses on the evolution of the tip velocity, from the early stage of the filament retraction until it reache

Inertial flow past a finite-length axisymmetric cylinder of aspect ratio 3: Effect of the yaw angle
Autor: Jean-Lou Pierson, Franck Auguste, Anthony Wachs, Abdelkader Hammouti

Physical Review Fluids, American Physical Society, 2019, 4 (4), pp.Art. n° 044802. ⟨10.1103/PhysRevFluids.4.044802⟩
International audience; We study the flow past a finite-length yawed three-dimensional cylinder by a finite-volume–fictitious-domain method. We validate our non-boundary-fitted method against boundary-fitted numerical results for a finite-length cy
