Arrest of Fluid Demixing by Nanoparticles: A Computer Simulation Study (2008)
Kim, E., Stratford, K., Adhikari, R., Cates, M. E.
We use lattice Boltzmann simulations to investigate the formation of arrested structures upon demixing of a binary solvent containing neutrally wetting colloidal particles. Previous simulations for...
Binary fluids under steady shear in three dimensions (2007)
Stratford, K., Desplat, J. -C., Stansell, P., Cates, M. E.
We simulate by lattice Boltzmann the steady shearing of a binary fluid mixture with full hydrodynamics in three dimensions. Contrary to some theoretical scenarios, a dynamical steady state is...
Nonequilibrium steady states in sheared binary fluids (2005)
Stansell, P., Stratford, K., Desplat, J. -C., Adhikari, R., Cates, M. E.
We simulate by lattice Boltzmann the steady shearing of a binary fluid mixture undergoing phase separation with full hydrodynamics in two dimensions. Contrary to some theoretical scenarios, a...
Colloidal Jamming at Interfaces: a Route to Fluid-bicontinuous Gels (2005)
Stratford, K., Adhikari, R., Pagonabarraga, I., Desplat, J. -C., Cates, M. E.
Colloidal particles or nanoparticles, with equal affinity for two fluids, are known to adsorb irreversibly to the fluid-fluid interface. We present large-scale computer simulations of the demixing of...
Sliding periodic boundary conditions for lattice Boltzmann and lattice kinetic equations (2005)
Adhikari, R., Desplat, J. -C., Stratford, K.
We present a method to impose linear shear flow in discrete-velocity kinetic models of hydrodynamics through the use of sliding periodic boundary conditions. Our method is derived by an explicit...
HPCx: towards capability computing (2005)
Ashworth, M, Bush, IJ, Guest, MF, Sunderland, AG, Booth, S, Hein, J, ...
We introduce HPCx - the UK's new National HPC Service - which aims to deliver a world-class service for capability computing to the UK scientific community. HPCx is targeting an environment that will...
Cates, M. E., Desplat, J. -C., Stansell, P., Wagner, A. J., Stratford, K., Adhikari, R., ...
We describe some scaling issues that arise when using lattice Boltzmann methods to simulate binary fluid mixtures -- both in the presence and in the absence of colloidal particles. Two types of...
Lattice Boltzmann for Binary Fluids with Suspended Colloids (2004)
Stratford, K., Adhikari, R., Pagonabarraga, I., Desplat, J. -C.
A new description of the binary fluid problem via the lattice Boltzmann method is presented which highlights the use of the moments in constructing two equilibrium distribution functions. This offers...
Simulating Colloid Hydrodynamics with Lattice Boltzmann (2004)
Cates, M. E., Stratford, K., Adhikari, R., Stansell, P., Desplat, J. -C., Pagonabarraga, I., ...
We present a progress report on our work on lattice Boltzmann methods for colloidal suspensions. We focus on the treatment of colloidal particles in binary solvents and on the inclusion of thermal...
Fluctuating lattice Boltzmann (2004)
Adhikari, R., Cates, M. E., Stratford, K., Wagner, A. J.
The lattice Boltzmann algorithm efficiently simulates the Navier Stokes equation of isothermal fluid flow, but ignores thermal fluctuations of the fluid, important in mesoscopic flows. We show how to...
