Advances in Computational Methods for Free-Surface Flows
TL;DR: In this article, a wide variety of mechanisms, including inhomogeneities or foreign matter in the coating solutions, disturbances induced by equipment vibration or uncontrolled air flow, various wetting phenomena, and flow instabilities that grow in a coating device but partially decay further downstream, almost exclusively arise from catastrophic hydrodynamic instabilities.

Efficient GPGPU implementation of a lattice Boltzmann model for multiphase flows with high density ratios
TL;DR: In this article, the Lattice Boltzmann Method (LBM) is used for numerical simulation of multiphase flows with high density ratios, such as found in ocean surface wave and air-sea interaction problems, and its efficient implementation on a massively parallel GPGPU.

A new incompressibility discretization for a hybrid particle MAC grid representation with surface tension
TL;DR: This work takes a particle based approach to incompressible free surface flow motivated by the fact that an explicit representation of the interface geometry and internal deformations gives precise feedback to an implicit solver for surface tension.

Volume of fluid (VOF) method for the dynamics of free boundaries
C.W Hirt,B. D. Nichols +1 more
TL;DR: In this paper, the concept of a fractional volume of fluid (VOF) has been used to approximate free boundaries in finite-difference numerical simulations, which is shown to be more flexible and efficient than other methods for treating complicated free boundary configurations.
