Simulation of Dynamic Rearrangement Events in Wall-Flow Filters Applying Lattice Boltzmann Methods
Fluids, 2023 Wall-flow filters are applied in the exhaust treatment of internal combustion engines for the removal of particulate matter (PM). Over time, the pressure drop inside those filters increases due to the continuously introduced solid material, which forms ...

Fluids, 2023 Rearrangement events in wall-flow filters lead to the formation of specific deposition patterns, which affect a filter’s pressure drop, its loading capacity and the separation efficiency.

Linear and brute force stability of orthogonal moment multiple-relaxation-time lattice Boltzmann methods applied to homogeneous isotropic turbulence [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2021 Multiple-relaxation-time (MRT) lattice Boltzmann methods (LBM) based on orthogonal moments exhibit lattice Mach number dependent instabilities in diffusive scaling. The present work renders an explicit formulation of stability sets for orthogonal moment MRT LBM. The stability sets are defined via the spectral radius of linearized amplification matrices

Direct simulation of liquid-gas-solid flow with a free surface lattice Boltzmann method [PDF]
, 2017 Direct numerical simulation of liquid-gas-solid flows is uncommon due to the considerable computational cost. As the grid spacing is determined by the smallest involved length scale, large grid sizes become necessary -- in particular if the bubble ...

Development of Holistic homogeneous model of selective laser melting based on Lattice Boltzmann method: Qualitative simulation [PDF]
AIP Conference Proceedings, 2020 Additive manufacturing (AM) technologies are developing fast in recent years. Many of them, such as Selective Laser Sintering/Melting (SLS/SLM) and also Laser Cladding, deal with materials in different states of matter that are changed during processing.

Journal of Fluid Science and Technology, 2014 Three-dimensional homogeneous isotropic turbulence simulations are conducted using moment-based lattice Boltzmann method and the large-eddy simulation based lattice Boltzmann method. for two Taylor's microscale Reynolds number, Reλ = 225 and Reλ = 314. On comparing the results obtained from these two methods, we found that the two methods produced
