Fluid-Structure Interaction with the Entropic Lattice Boltzmann Method
Benedikt Dorschner, Shyam S. Chikatamarla, Ilya V. Karlin
We propose a novel fluid-structure interaction (FSI) scheme using the entropic multi-relaxation time lattice Boltzmann (KBC) model for the fluid domain in combination with a nonlin…
Grid refinement for entropic lattice Boltzmann models
B. Dorschner, N. Frapolli, S. S. Chikatamarla +1
We propose a novel multi-domain grid refinement technique with extensions to entropic incompressible, thermal and compressible lattice Boltzmann models. Its validity and accuracy a…
Entropic Lattice Boltzmann Method for Moving and Deforming Geometries in Three Dimensions
B. Dorschner, S. S. Chikatamarla, I. V. Karlin
Entropic lattice Boltzmann methods have been developed to alleviate intrinsic stability issues of lattice Boltzmann models for under-resolved simulations. Its reliability in combin…
Drops bouncing off macro-textured superhydrophobic surfaces
Ali Mazloomi Moqaddam, Shyam S. Chikatamarla, Ilya Karlin
Recent experiments with droplets impacting a macro-textured superhydrophobic surfaces revealed new regimes of bouncing with a remarkable reduction of the contact time. We present h…
Entropic multi-relaxation lattice Boltzmann scheme for turbulent flows
Fabian Bösch, Shyam S. Chikatamarla, Ilya Karlin
We present three dimensional realizations of the model introduced recently by (Karlin, Bösch, Chikatamarla, Phys. Rev. E 2014) and review the role of the entropic stabilizer. The p…
Entropic Multi-Relaxation Models for Simulation of Fluid Turbulence
Fabian Bösch, Shyam S. Chikatamarla, Ilya Karlin
A recently introduced family of lattice Boltzmann (LB) models (Karlin, Bösch, Chikatamarla, Phys. Rev. E, 2014) is studied in detail for incompressible two-dimensional flows. A fra…
Comment on the paper J. G. Zhou, Rectangular lattice Boltzmann method, Phys. Rev. E 81, 026705 (2010)
Shyam Chikatamarla, Ilya Karlin
It is shown both analytically and numerically that the suggested lattice Boltzmann model on rectangular grids leads to anisotropic dissipation of fluid momentum and thus it does no…
Factorization symmetry in lattice Boltzmann simulations
Ilya Karlin, Shyam Chikatamarla, Pietro Asinari
A non-perturbative algebraic theory of lattice Boltzmann method is developed based on a symmetry of a product. It involves three steps: (i) Derivation of admissible lattices in one…
Quasi-Equilibrium Lattice Boltzmann Method
S. Ansumali, S. Arcidiacono, S. Chikatamarla +3
A general lattice Boltzmann method for simulation of fluids with tailored transport coefficients is presented. It is based on the recently introduced quasi-equilibrium kinetic mode…
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…
