Entropic Lattice Boltzmann Simulation of the Flow Past Square Cylinder
Santosh Ansumali, Shyam Sunder Chikatamarla, Christos Emmanouil Frouzakis +1
Minimal Boltzmann kinetic models, such as lattice Boltzmann, are often used as an alternative to the discretization of the Navier-Stokes equations for hydrodynamic simulations. Rec…
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…
