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…
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…
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…
Studies of accurate multi-component lattice Boltzmann models on benchmark cases required for engineering applications
Hiroshi Otomo, Hongli Fan, Yong Li +4
We present recent developments in lattice Boltzmann modeling for multi-component flows, implemented on the platform of a general purpose, arbitrary geometry solver PowerFLOW. Prese…
Simulation of residual oil displacement in a sinusoidal channel with the lattice Boltzmann method
Hiroshi Otomo, Hongli Fan, Randy Hazlett +4
We simulate oil slug displacement in a sinusoidal channel in order to validate computational models and algorithms for multi-component flow. This case fits in the gap between fully…
The Effect of Small-Scale Forcing on Large-Scale Structures in Two-Dimensional Flows
Alexei Chekhlov, Steven A. Orszag, Semion Sukoriansky +2
The effect of small scale forcing on large scale structures in -plane two-dimensional (2D) turbulence is studied using long-term direct numerical simulations (DNS). We find that…
Large eddy simulation of two-dimensional isotropic turbulence
Semion Sukoriansky, Alexei Chekhlov, Boris Galperin +1
Large eddy simulation (LES) of forced, homogeneous, isotropic, two-dimensional (2D) turbulence in the energy transfer subrange is the subject of this paper. A difficulty specific t…
