Consistent Lattice Boltzmann Method
S. Ansumali, I. V. Karlin
The problem of energy conservation in the lattice Boltzmann method is solved. A novel model with energy conservation is derived from Boltzmann's kinetic theory. It is demonstrated…
Exploring Hydrodynamic Closures for the Lid-driven Micro-cavity
S. Ansumali, C. E. Frouzakis, I. V. Karlin +1
A minimal kinetic model is used to study analytically and numerically flows at a micrometer scale. Using the lid-driven microcavity as an illustrative example, the interplay betwee…
Entropic lattice Boltzmann method for microflows
S. Ansumali, I. V. Karlin, C. E. Frouzakis +1
A new method for the computation of flows at the micrometer scale is presented. It is based on the recently introduced minimal entropic kinetic models. Both the thermal and isother…
Kinetic Theory of Turbulence Modeling: Smallness Parameter, Scaling and Microscopic Derivation of Smagorinsky Model
Santosh Ansumali, Iliya V. Karlin, Sauro Succi
A mean-field approach (filtering out subgrid scales) is applied to the Boltzmann equation in order to derive a subgrid turbulence model based on kinetic theory. It is demonstrated…
Existence of the H theorem for the athermal lattice Boltzmann models with nonpolynomial equilibria
Santosh Ansumali, Iliya V. Karlin
The entropy function is found for the two-dimensional seven-velocity lattice Boltzmann method on a triangular lattice. Some issues pertinent to the stability and accuracy of the se…
Entropic Lattice Boltzmann Method for Large Scale Turbulence Simulation
I. V. Karlin, S. Ansumali, E. DE Angelis +2
Recently, a minimal kinetic model for fluid flow, known as entropic lattice Boltzmann method, has been proposed for the simulation of isothermal hydrodynamic flows. At variance wit…
