In this article we demonstrate that the standard Einstein–Helfand formulas are valid for systems containing dissipative and random forces provided that: (i) conservation laws are satisfied, and (ii) transition probabilities satisfy detailed balance

An angular momentum conservative pure bulk viscosity term for Smoothed Particle Hydrodynamics is proposed in the present paper. This formulation permits to independently model shear and bulk viscosities, which is of paramount importance for fluids wi

Modelling capillary phenomena at a mesoscale: From simple to complex fluids

Autor: J. Bonet-Avalos, Samy Merabia, Ignacio Pagonabarraga

Publikováno v: Journal of Non-Newtonian Fluid Mechanics. 154:13-21

A mesoscopic model for studying capillary phenomena is introduced. The fluid is represented by particles interacting through soft forces that allow condensation. A model for a solid wall is also presented whose affinity for the liquid can be tuned fr

We describe adsorption of neutral flexible polymer chains onto small colloids that can be covered by one chain. We discuss the structure of star-shaped complexes and their abundance in dilute solution. In semi-dilute solution similar complexes form c
