Molecular dynamics perspectives on nonideal fluid models for the lattice Boltzmann method
Hiroshi Otomo, Alexander J. Wagner
Despite their widespread use, mesoscopic models for non-ideal fluids have rarely been systematically validated against microscopic simulations. In this work, molecular dynamics (MD…
Enhanced numerical models for two-component fluid flow in multiscale porous structures
J. Yang, H. Otomo, Hongli Fan +6
Multi-component fluid flow simulations in multi-scale porous structures often involve regions that are under-resolved at practical computational resolutions. Accurately capturing t…
Capillary flow simulation with the phase-field-based lattice Boltzmann solver
R. Thirumalaisamy, S. Kim, H. Otomo +2
The phase-field-based lattice Boltzmann (LB) model has been developed to perform high fidelity multiphase flow simulations. Its ability to accurately handle high density ratio and…
Lattice Boltzmann models for the hydrodynamic equations in multiphase flow with high density ratio
H. Otomo, C. Sun, T. Inamuro +5
Multiphase flows with high density ratios, such as water and air flows, have recently been simulated using the lattice Boltzmann (LB) method. This approach corresponds to solving t…
A simulation approach including under-resolved scales for multi-component fluid flows in multi-scale porous structures
Hiroshi Otomo, Rafael Salazar-Tio, Jingjing Yang +5
In this study, we develop computational models and methodology for accurate multi-component-flow simulation in under-resolved multi-scale porous structures. It is generally impract…
