“…From some preliminary results in a turbulent flow (e.g., Fig. 8 in [9]), the noisy results of the local physics are likely related to the flaws in the refilling scheme. We will demonstrate that, if the refilling scheme is not properly implemented, it can be a source of significant problems affecting both the accuracy of the force evaluation and the numerical stability of fluid-particle systems, especially when the flow and particle Reynolds numbers are high.…”

“…As an alternative approach, lattice Boltzmann method (LBM) has also been applied as a PRS method for turbulent particleladen flows [10,8,9]. The LBM approach features a high-level data locality essential to efficient implementation of PRS.…”

“…In recent years, several PRS methods based on the Navier-Stokes (N-S) equation have been developed, with the particle-fluid interfaces treated by the immersed boundary method [2,3], direct-forcing [4], local analytical treatment [5], overset grid [1], force-coupling [6], or penalization method [7]. As reviewed in [8,9], these studies have contributed to the understanding of flow modulation by the inertial particles and the dynamic effects due to finite particle size.…”

a b s t r a c tIn this work, we revisit implementation issues in the lattice Boltzmann method (LBM) concerning moving rigid solid particles suspended a viscous fluid. Three aspects relevant to the interaction between flow of a viscous fluid and moving solid boundaries are considered. First, the popular interpolated bounce back scheme is examined both theoretically and numerically. It is important to recognize that even though significant efforts had previously been devoted to the performance, especially the accuracy, of different interpolated bounce back schemes for a fixed boundary, there were relatively few studies focusing on moving solid surfaces. In this study, different interpolated bounce back schemes are compared theoretically for a moving boundary. Then, several benchmark cases are presented to show their actual performance in numerical simulations. Second, we examine different implementations of the momentum exchange method to calculate hydrodynamic force and torque acting on a moving surface. The momentum exchange method is well established for fixed solid boundaries, however, for moving solid boundaries there are still open issues such as unphysical force fluctuations and Galilean invariance errors. Recent progress in this direction is discussed, along with our own interpretations and modifications. Several benchmark cases, including a particle-laden turbulent channel flow, are used to demonstrate the effects of different modifications on the accuracy and physical results under different physical configurations. The third aspect is the refilling scheme for constructing the unknown distribution functions for the new fluid nodes that emerge from the previous solid region as a particle moves relative to a fixed lattice grid. We examine and compare the performance of the refilling schemes introduced by Fang et al. (2002), Caiazzo (2008). We demonstrate that improvements can be made to suppress force fluctuations resulting from refilling.

“…Using the lattice Boltmzann method coupled with the momentum exchange method, Wang et al [85][86][87] made a comparative analysis to single-phase turbulence and particle-laden turbulence and studied a decaying isotropic turbulence laden with finite-size particles of Kolmogorov to Taylor microscale sizes. Zhang et al [88,89] investigated the differential settling of cohesive sediment and the non-equilibrium flocculation of cohesive sediments in homogeneous turbulent flows.…”

“…This suggests that, in turbulent flow, motions of finite size particles can produce small-scale flow structures near their surfaces. The two-dimensional visualizations of the vorticity magnitude and the particle scatter are provided by horizontally cutting the fluid through the slice near the center of the domain [86,87]. The compuational domain is 256 3 and contains 6400 rigid particles with uniform diameter 8 lattice units.…”

Abstract:As a native scheme to evaluate hydrodynamic force in the lattice Boltzmann method, the momentum exchange method has some excellent features, such as simplicity, accuracy, high efficiency and easy parallelization. Especially, it is independent of boundary geometry, preventing from solving the Navier-Stokes equations on complex boundary geometries in the boundary-integral methods. We review the origination and main developments of the momentum exchange method in lattice Boltzmann simulations. Then several practical techniques to fill newborn fluid nodes are discussed for the simulations of fluid-structure interactions. Finally, some representative applications show the wide applicability of the momentum exchange method, such as movements of rigid particles, interactions of deformation particles, particle suspensions in turbulent flow and multiphase flow, etc.
