Colloids are ubiquitous in the food, medical, cosmetics, polymers, water purification, and pharmaceutical industries. The thermal, mechanical, and storage properties of colloids are highly dependent on their interface morphology and their rheological behavior. Numerical methods provide a convenient and reliable tool for the study of colloids. Accelerated Lattice Boltzmann Model for Colloidal Suspensions introduce the main building-blocks for an improved lattice Boltzmann–based numerical tool designed for the study of colloidal rheology and interface morphology. This book also covers the migrating multi-block used to simulate single component, multi-component, multiphase, and single component multiphase flows and their validation by experimental, numerical, and analytical solutions. Among other topics discussed are the hybrid lattice Boltzmann method (LBM) for surfactant-covered droplets; biological suspensions such as blood; used in conjunction with the suppression of coalescence for investigating the rheology of colloids and microvasculature blood flow. The presented LBM model provides a flexible numerical platform consisting of various modules that could be used separately or in combination for the study of a variety of colloids and biological flow deformation problems.

ABSTRACT: We investigate the dynamic and static properties of polymeric suspensions via a numerical simulation method. This method couples Newtonian mechanics of solid phase suspended particles with a fluctuating lattice-Boltzmann fluid. This results in the solution of the Navier-Stokes equation, including thermal fluctuations and hydrodynamic interactions for the solid particles. The coupling can be achieved either through boundary conditions for a finite sized particle or through a Stokes-like frictional coupling for point particles. The frictional coupling procedure is a very efficient approach due to the use of point particles which take up much smaller volumes. This in turn results in simulations of far fewer lattice nodes, while retaining essential hydrodynamic features for dynamics of polymers. This approach has enabled us to simulate polymer chains with more than 1000 segments, including hydrodynamic interactions. This discretization is nearly an order of magnitude higher than what is feasible using traditional Brownian dynamics methods. The fluctuating lattice-Boltzmann method is presented for both colloidal and polymeric suspensions. A verification of the fluctuations for the case of colloidal finite sized particles is presented as a test case. However, the main theme of this thesis is the simulations of dilute polymer solutions.

The main objective of the book is to highlight the modeling of magnetic particles with different shapes and magnetic properties, to provide graduate students and young researchers information on the theoretical aspects and actual techniques for the treatment of magnetic particles in particle-based simulations. In simulation, we focus on the Monte Carlo, molecular dynamics, Brownian dynamics, lattice Boltzmann and stochastic rotation dynamics (multi-particle collision dynamics) methods. The latter two simulation methods can simulate both the particle motion and the ambient flow field simultaneously. In general, specialized knowledge can only be obtained in an effective manner under the supervision of an expert. The present book is written to play such a role for readers who wish to develop the skill of modeling magnetic particles and develop a computer simulation program using their own ability. This book is therefore a self-learning book for graduate students and young researchers. Armed with this knowledge, readers are expected to be able to sufficiently enhance their skill for tackling any challenging problems they may encounter in future.
