Average turbulence dynamics from a one-parameter kinetic theory
Hudong Chen, Ilya Staroselsky, Katepalli R. Sreenivasan +1
We show theoretically that the mean turbulent dynamics can be described by a kinetic theory representation with a single free relaxation time that depends on space and time. A prop…
Volumetric Lattice Boltzmann Models in General Curvilinear Coordinates: Theoretical Formulation
Hudong Chen
A theoretical formulation of lattice Boltzmann models on a general curvilinear coordinate system is presented. It is based on a volumetric representation so that mass and momentum…
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…
