Generalized lattice Boltzmann method with multirange pseudopotential.
The physical behavior of a class of mesoscopic models for multiphase flows is analyzed in details near interfaces. In particular, an extended pseudopotential method is developed, which permits to tune the equation of state and surface tension independently of each other. The spurious velocity contributions of this extended model are shown to vanish in the limit of high grid refinement and/or hi...
متن کاملPRO O F CO PY [ EJ 10592 ] 134912 PRE Graphics processing unit implementation
A graphic processing unit GPU implementation of the multicomponent lattice Boltzmann equation with multirange interactions for soft-glassy materials “glassy” lattice Boltzmann LB is presented. Performance measurements for flows under shear indicate a GPU/CPU speed up in excess of 10 for 10242 grids. Such significant speed up permits to carry out multimillion time-steps simulations of 10242 grid...
متن کاملNumerical analysis of gas flows in a microchannel using the Cascaded Lattice Boltzmann Method with varying Bosanquet parameter
Abstract. In this paper, a Cascaded Lattice Boltzmann Method with second order slip boundary conditions is developed to study gas flows in a microchannel in the slip and transition flow regimes with a wide range of Knudsen numbers. For the first time the effect of wall confinement is considered on the effective mean free path of the gas molecules using a function with nonconstant Bosanquet para...
متن کاملImplementation of D3Q19 Lattice Boltzmann Method with a Curved Wall Boundary Condition for Simulation of Practical Flow Problems
In this paper, implementation of an extended form of a no-slip wall boundary condition is presented for the three-dimensional (3-D) lattice Boltzmann method (LBM) for solving the incompressible fluid flows with complex geometries. The boundary condition is based on the off-lattice scheme with a polynomial interpolation which is used to reconstruct the curved or irregular wall boundary on the ne...
متن کاملUsing the Lattice Boltzmann Method for the numerical study of non-fourier conduction with variable thermal conductivity
The lattice Boltzmann method (LBM) was used to analyze two-dimensional (2D) non-Fourier heat conduction with temperature-dependent thermal conductivity. To this end, the evolution of wave-like temperature distributions in a 2D plate was obtained. The temperature distributions along certain parts of the plate, which was subjected to heat generation and constant thermal conductivity condit...
