Accelerated Lattice Boltzmann Model for Colloidal Suspensions

This book introduces an improved LBM tool for the study of colloidal rheology and interface morphology. Also covers the migrating multi-block used to simulate single and multi-component, multiphase, and single component multiphase flows and their validation.

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 Boltzmannbased 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.

Provides an efficient LBM based numerical model for the study of colloids and in particular emulsions and biological fluids Presents three novel schemes for the improvement of the multi-phase LBM manely the migrating multi-block, surfactant covered droplets and suppression of coalescence with attached pseudo-code Explores a large variety of physics of fluids, such as buoyancy, shear lift, coalescence, droplets deformation, aggregation and disaggregation and rheology of emulsions
