A Lattice Boltzmann model for diffusion of binary gas mixtures
This thesis describes the development of a Lattice Boltzmann (LB) model for a binary gas mixture. Specifically, channel flow driven by a density gradient with diffusion slip occurring at the wall is studied in depth. The first part of this thesis sets the foundation for the multi-component model …

Anwendung des Lattice-Boltzmann-Verfahrens zur Berechnung strömungsakustischer Probleme
The Lattice-Boltzmann-model is analyzed with regard to application to numerical solution of flow acoustic problems. In the first part of this study the description of sound wave propagation by common variants of the Lattice-Boltzmann-model is examined by calculation of phase velocity and effective …

Specialized Inter-Particle Interaction Lbm For Patterned Superhydrophobic Surfaces
… wetting characteristics. The Shan and Chen (SC) lattice Boltzmann model (LBM) is a good numerical tool, which holds strong potentials to qualify for simulating droplets wettability. This is due to its realistic nature of droplet contact angle (CA) prediction on flat smooth surfaces. But SC-LBM …

Simulation of two-phase dynamics using lattice boltzmann method (LBM)
In this dissertation, a new lattice Boltzmann model, called the artificial interface lattice Boltzmann model (AILB model), is proposed for the simulation of two-phase dynamics. The model is based on the principle of free energy minimization and invokes the Gibbs-Duhem equation in the formulation of …

A Lattice Boltzmann method model of diffusion-weighted magnetic resonance imaging in skeletal muscle
… on the effective diffusion coefficient via a Lattice Boltzmann model (LBM). Specifically, we aim to characterize how variations in microstructure and mass transport properties affect the local apparent diffusion coefficient of water measured with Diffusion Tensor Imaging (DTI). A numerical …

Lattice Boltzmann method for integrating the Bloch equation in muscle fibers and microvessels
… focus of this thesis is the development of a Lattice Boltzmann model of a single muscle fiber that can be parallelized in the future to include an ordered or disordered array of myofibrils and lipid domains inside the muscle fiber, and numerically simulate the multiphase transport of water, …

The production of pure hydrogen with simultaneous capture of carbon dioxide
… on the active surface area of the iron oxide. A lattice Boltzmann model, which incorporates hydrodynamics, mass transport and reaction, was developed. The composition of the solid changed with time. Quantitative agreement between the model and experiments for the reduction of a single particle of …

Lattice-gas cellular automata for the analysis of cancer invasion
… Cellular automata (CA) can be viewed as simple models of self-organizing complex systems in which collective behavior can emerge out of an ensemble of many interacting "simple" components. In particular, we focus on an important class of CA, the so-called lattice-gas cellular automata …
