A new high-order particle method for solving high Reynolds number incompressible flows
TL;DR: The proposed high-order particle method combines the advantages of particle and mesh methods to approximate the total and the spatial derivative terms under the Lagrangian and the Eulerian frameworks to avoid convective instability and increase solution accuracy.

Modelling fluid–structure interactions: a survey of methods and experimental verification
Diana De Padova,Michele Mossa +1 more
TL;DR: It is difficult to study fluid structure interaction (FSI) problems using analytical methods due to flow non-linearity and multiphysics, so the main emphasis for research is placed on the a priori determinants of FSI.

Dissertation
Development of Smoothed Particle Hydrodynamics approach for modelling of multiphase flows with interfaces
TL;DR: An important part of work is a thorough comparison of two different incompressibility treatments: the weakly compressible approach, where a suitably chosen equation of state is used, and truly incompressible method, where the velocity field is projected onto a divergence-free space.

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.
