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…
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…
Lattice Boltzmann Model in General Curvilinear Coordinates Applied to Exactly Solvable 2D Flow Problems
Alexei Chekhlov, Ilya Staroselsky, Raoyang Zhang +1
Numerical simulation results of basic exactly solvable fluid flows using the previously proposed Lattice Boltzmann Method (LBM) formulated on a general curvilinear coordinate syste…
Filtered Lattice Boltzmann Collision Formulation Enforcing Isotropy and Galilean Invariance
Hudong Chen, Raoyang Zhang, Pradeep Gopalakrishnan
The central framework of a filtered lattice Boltzmann collision operator formulation is to remove hydrodynamic moments that are not supported by the order of isotropy of a given la…
Improved phase-field-based lattice Boltzmann models with a filtered collision operator
Hiroshi Otomo, Raoyang Zhang, Hudong Chen
In this study, a phase-field lattice Boltzmann model based on the Allen-Cahn equation with a filtered collision operator and high-order corrections in the equilibrium distribution…
Multi-component lattice Boltzmann models for accurate simulation of flows with wide viscosity variation
Hiroshi Otomo, Bernd Crouse, Marco Dressler +4
Multi-component lattice Boltzmann models operating in a wide range of fluid viscosity values are developed and examined. The algorithm is constructed with the goal to enable engine…
