Entropy-Assisted Computing of Low-Dissipative Systems

Autor: Ilya V. Karlin, Fabian Bösch, Shyam S. Chikatamarla, Sauro Succi

Publikováno v: Entropy, Vol 17, Iss 12, Pp 8099-8110 (2015)

Entropy feedback is reviewed and highlighted as the guiding principle to reach extremely low dissipation. This principle is illustrated through turbulent flow simulations using the entropic lattice Boltzmann scheme.

Semi-Lagrangian lattice Boltzmann model for compressible flows on unstructured meshes

Autor: Mohammad Hossein Saadat, Iliya V. Karlin, Fabian Bösch

Publikováno v: Physical Review E
Physical Review E, 101 (2)

Compressible lattice Boltzmann model on standard lattices [M. H. Saadat, F. Bösch, and I. V. Karlin, Phys. Rev. E 99, 013306 (2019).] is extended to deal with complex flows on unstructured grid. Semi-Lagrangian propagation [A. Krämer et al., Phys.

Lattice Boltzmann model for compressible flows on standard lattices: Variable Prandtl number and adiabatic exponent

Autor: Mohammad Hossein Saadat, Fabian Bösch, Ilya V. Karlin

Publikováno v: Physical Review E, 99 (1)

A lattice Boltzmann model for compressible flows on standard lattices is developed and analyzed. A consistent two-population thermal lattice Boltzmann is used which allows a variable Prandtl number and a variable adiabatic exponent, and appropriate c

Entropic multi-relaxation time lattice Boltzmann model for complex flows

Autor: Fabian Bösch, Shyam S. Chikatamarla, Ilya V. Karlin, Benedikt Dorschner, Konstantinos Boulouchos

Publikováno v: Journal of Fluid Mechanics. 801:623-651

Entropic lattice Boltzmann methods were introduced to overcome the stability issues of lattice Boltzmann models for high Reynolds number turbulent flows. However, to date their validity has been investigated only for simple flows due to the lack of a

Particles-on-Demand for Kinetic Theory

Autor: Fabian Bösch, Iliya V. Karlin, Benedikt Dorschner

Publikováno v: Physical Review Letters, 121 (13)

A novel formulation of fluid dynamics as a kinetic theory with tailored, on-demand constructed particles removes any restrictions on Mach number and temperature as compared to its predecessors, the lattice Boltzmann methods and their modifications. I

Grad's approximation for moving and stationary walls in entropic lattice Boltzmann simulations

Autor: Iliya V. Karlin, Benedikt Dorschner, Fabian Bösch, Shyam S. Chikatamarla

Publikováno v: Journal of Computational Physics. 295:340-354

We introduce a new generalized wall boundary condition for the entropic lattice Boltzmann method (ELBM) that is capable of handling complex flow geometries including moving walls. The Grad's ten moments approximation is employed to approximate the mi

Entropic multi-relaxation free-energy lattice Boltzmann model for two-phase flows

Autor: Iliya V. Karlin, Benedikt Dorschner, Fabian Bösch

Publikováno v: EPL, 122 (1)

The entropic multi-relaxation lattice Boltzmann method is extended to two-phase systems following the free-energy approach. Gain in stability is achieved by incorporating the force term due to Korteweg's stress into the redefined entropic stabilizer,

Entropic multirelaxation lattice Boltzmann models for turbulent flows

Autor: Fabian Bösch, Shyam S. Chikatamarla, Ilya V. Karlin

Publikováno v: Physical Review E. 92

We present three-dimensional realizations of a class of lattice Boltzmann models introduced recently by the authors [I. V. Karlin, F. Bösch, and S. S. Chikatamarla, Phys. Rev. E 90, 031302(R) (2014)] and review the role of the entropic stabilizer. B
