TL;DR: A lattice Boltzmann interface capturing method for incompressible flows that does not require the isotropic property of the fourth order lattice tensor and can generate very sharp interfaces.
Abstract: A lattice Boltzmann interface capturing method for incompressible flows is proposed in this paper. The interface is naturally captured by minimizing the free energy functional. It is easily implemented and does not require interface reconstruction as required by most of the traditional interface tracking methods such as the volume of fluid method. Moreover, the method does not require the isotropic property of the fourth order lattice tensor as do other lattice Boltzmann methods. Thus the D2Q5 (D2 means two dimensional, Q5 means five velocity model) discrete velocity model is applied in the method. The interface profile along the flat interface and coexistence curve can be given analytically. The proposed method is validated for some test cases, and compared to the volume of fluid and level set methods. Numerical results show that the present method performs very well and can generate very sharp interfaces.

TL;DR: In this paper, a dual-grid approach is adopted to resolve the bulk scale with information from the fluid fine scale, which is shown to deliver more accuracy than a standard approach based on the volume averaging technique, still, it remains suitable for the solution of real interest problems.

TL;DR: In this paper, the authors used a computational fluid dynamics (CFD) approach to study sand particle erosion in elbows, while the carrier fluid was multiphase flow of low, medium, and high gas flow rates.
