New instability and mixing simulations using SPH and a novel mixing measure

Autor: Steven Lind, Benedict D. Rogers, Georgios Fourtakas, Georgina Reece

Publikováno v: Journal of Hydrodynamics. 32:684-698

This paper assesses the ability of smoothed particle hydrodynamics (SPH) to simulate mixing of two-phase flows and their transition to instabilities under different flow regimes. A new measure for quantification of the degree of mixing between phases

High-order simulations of isothermal flows using the local anisotropic basis function method (LABFM)

Autor: Jack King, Steven Lind

Mesh-free methods have significant potential for simulations of flows in complex geometries, with the difficulties of domain discretisation greatly reduced. However, many mesh-free methods are limited to low order accuracy. In order to compete with c

Dynamic boundary conditions (DBC) for solid surfaces are standard in the weakly compressible smoothed particle hydrodynamics (SPH) code DualSPHysics. A stationary solid is simply represented by fixed particles with pressure from the equation of state
