“…An interesting observation in this respect is the decreasing power dissipation by the dispersion concomitant with increasing colloidal alignment, which might place this ordering phenomenon within the wider-yet still incompletely understood-context of dissipative non-equilibrium steady states. 48,49 An important difference between the simulation approach advocated here and the approaches taken by most authors studying colloids in viscoelastic fluids 13,20,21,51 is that we do not employ a numerical Navier-Stokes solver to explicitly calculate the flow field throughout the entire simulation box. The RaPiD approach drastically reduces the computational burden, thereby enabling RaPiD to simulate larger systems with more colloids and in full three-dimensional space.…”

“…The problem of simulating colloids dispersed in viscoelastic fluids has been considered before by a number of groups, using lattice methods and Stokesian approaches to calculate flow fields subject to the boundary conditions posed by the colloids. Feng et al, 10 Binous and Phillips, Harlen, 12 Yu et al, 13 and Ardekani et al 14 simulated one and two spheres sedimenting through a viscoelastic fluid. Hwang et al 15 studied kissing and tumbling of two colloids in shear flow and observed strong shear-induced elongational flows between six colloids.…”

“…D'Avino et al [17][18][19] analyzed the rotation of a particle in a sheared viscoelastic liquid, and the shear-induced migration of a particle towards a wall. Flowinduced aggregation of a dozen colloids in a viscoelastic solution was simulated by Yu et al 13 for sedimenting particles and by Phillips and Talini 20 and Hwang and Hulsen 21 for suspensions exposed to a shear flow. We note that these studies have in common that the three-dimensional calculations have been limited to one and two colloidal particles in a viscoelastic fluid, while simulations with up to a dozen colloids were all restricted to two dimensions.…”

We investigate the shear-induced structure formation of colloidal particles dissolved in nonNewtonian fluids by means of computer simulations. The two investigated visco-elastic fluids are a semi-dilute polymer solution and a worm-like micellar solution. Both shear-thinning fluids contain long flexible chains whose entanglements appear and disappear continually as a result of Brownian motion and the applied shear flow. To reach sufficiently large time and length scales in threedimensional simulations with up to 96 spherical colloids, we employ the responsive particle dynamics simulation method of modeling each chain as a single soft Brownian par...

“…It is also attested that the arrangement itself of the Lagrangian particle nodes may alter results. For spheres, the best results are obtained with nodes adequately arranged in concentric shells and with the nodes closest to the particle surface slightly retracted from it [25,39]. A generalization to arbitrary-shaped particles is believed to be tedious.…”

Low Reynolds number concentrated suspensions do exhibit an intricate physics which can be partly unraveled by the use of numerical simulation. To this end, a Lagrange multiplier-free fictitious domain approach is described in this work. Unlike some methods recently proposed, the present approach is fully Eulerian and therefore does not need any transfer between the Eulerian background grid and some Lagrangian nodes attached to particles. Lubrication forces between particles play an important role in the suspension rheology and have been properly accounted for in the model. A robust and effective lubrication scheme is outlined which consists in transposing the classical approach used in Stokesian Dynamics to our present direct numerical simulation. This lubrication model has also been adapted to account for solid boundaries such as walls. Contact forces between particles are modeled using a classical Discrete Element Method (DEM), a widely used method in granular matter physics. Comprehensive validations are presented on various one-particle, two-particle or three-particle configurations in a linear shear flow as well as some O(10 3 ) and O(10 4 ) particle simulations.
