Thermal fluctuations cause perturbations of fluid-fluid interfaces and highly nonlinear hydrodynamics in multiphase flows. In this work, we develop a multiphase smoothed dissipative particle dynamics (SDPD) model. This model accounts for both bulk hydrodynamics and interfacial fluctuations. Interfacial surface tension is modeled by imposing a pairwise force between SDPD particles. We show that the relationship between the model parameters and surface tension, previously derived under the… 
Continuum Model for Nanoscale Multiphase Flows
We propose a nonlocal model for surface tension. This model, in combination with the Landau-Lifshitz-Navier-Stokes equations, describes mesoscale features of the multiphase flow, including the static
A Smooth Dissipative Particle Dynamics method for nonisothermal liquid and gas flows in bounded domains
SDPD-DV simulations for liquid H 2 O, gaseous Ar and N 2 systems under thermal equilibrium assess the impact of the ratio of particle mass over the real molecular mass and the size of smoothing length on fluid properties, hydrodynamic fluctuations and transport coefficients.
An arbitrary Lagrangian Eulerian smoothed particle hydrodynamics (ALE-SPH) method with a boundary volume fraction formulation for fluid-structure interaction.
A new weakly-compressible smoothed particle hydrodynamics method capable of modeling non-slip fixed and moving wall boundary conditions and extends the transport-velocity formulation to reaction-diffusion transport of mass in Newtonian fluids and linear elastic solids, which is common in biological structures.
Numerical investigation of microscale dynamic contact angles of the CO2–water–silica system using coarse-grained molecular approach
The dynamic contact angle of a gas–liquid–solid system depends on the contact line velocity and ignoring this effect could lead to inaccurate estimations of the capillary pressures in microporous
Everything you always wanted to know about SDPD⋆ (⋆but were afraid to ask)
An overview of the smoothed dissipative particle dynamics (SDPD) method is presented in a format that tries to quickly answer questions that often arise among users and newcomers. It is hoped that

Debris-covered glaciers are increasingly studied because it is assumed that debris cover extent and thickness could increase in a warming climate, with more regular rockfalls from the surrounding
It is shown that the full set of hydromagnetic equations admit five more integrals, besides the energy integral, if dissipative processes are absent, which made it possible to formulate a variational principle for the force-free magnetic fields.
