Lattice Boltzmann modeling of Bingham plastics

Wang, Chen-Hao; Ho, Jeng-Rong - In: Physica A: Statistical Mechanics and its Applications 387 (2008) 19, pp. 4740-4748

A new lattice Boltzmann model within the framework of D2Q9 lattices for Bingham plastics is proposed. The essence of the present model lies in incorporation of the effect of local shear rate into the lattice equilibrium distribution function. With this arrangement, particle distribution...

Nonequilibrium entropy limiters in lattice Boltzmann methods

Brownlee, R.A.; Gorban, A.N.; Levesley, J. - In: Physica A: Statistical Mechanics and its Applications 387 (2008) 2, pp. 385-406

We construct a system of nonequilibrium entropy limiters for the lattice Boltzmann methods (LBM). These limiters erase spurious oscillations without blurring of shocks, and do not affect smooth solutions. In general, they do the same work for LBM as flux limiters do for finite differences,...

Two-dimensional lattice Boltzmann model for compressible flows with high Mach number

Gan, Yanbiao; Xu, Aiguo; Zhang, Guangcai; Yu, Xijun; … - In: Physica A: Statistical Mechanics and its Applications 387 (2008) 8, pp. 1721-1732

In this paper we present an improved lattice Boltzmann model for compressible Navier–Stokes system with high Mach number. The model is composed of three components: (i) the discrete-velocity-model by M. Watari and M. Tsutahara [Phys. Rev. E 67 (2003) 036306], (ii) a modified Lax–Wendroff...
