21. Zero and Multi-Dimensional Modeling of Internal Combustion Engines with respect to Ion Current and Soot Formation
Abstract : The work presented in this thesis can be divided into the three following fields of investigation: First of all the ionization model developed in this thesis is meant to simulate the thermal ionization process or the so-called second peak. Equilibrium assumptions have been adopted for the modeling of the thermal ionization, in which Saha’s equation was derived for singly ionized molecules. READ MORE

22. Continuum modeling of particle flows in high shear granulation
Abstract : High shear granulation is an important process in the pharmaceutical industry. The aim of the process is to produce granules with specific properties, like size and hardness, from powder mixtures. The properties of the granules are determined by the flow field in the mixer. READ MORE

23. Numerical Modeling of Turbulent Gas-Particle Flow
Abstract : This work presents a theoretical and numerical study of gas-particle two-phase flow within the Eulerian framework. Although gas-particle flows have been extensively studied, there is still no general agreement on the constitutive equations for an Eulerian-Eulerian model in which the dispersed phase is treated as a continuum, i.e. a granular fluid.

24. Kinetic Studies of NOx Storage and Reduction Catalysts - Flow Reactor Experiments and Microkinetic Modeling
Abstract : The NOx storage and reduction (NSR) technology is a promising technique to reduce NOx during oxygen excess e.g. in lean burn engine exhaust. A typical NSR catalyst consists of the following components: precious metals, such as platinum, palladium or rhodium, a storage component, usually barium, and a high surface area support, such as γ-alumina.

25. Towards Prospective Exposure Modeling of Nanoparticles - Applying Particle Flow Analysis and Kinetic Exposure Modeling for the Cases of TiO2 and Ag Nanoparticles
Abstract : The claims regarding the usefulness of nanoparticles (NPs) in different applications, such as wound dressings, solar cells and soil remediation, has been accompanied by concern that NPs may also pose risks to humans and to the environment. Considering the past century, when many substances later shown to cause unacceptable damage were manufactured in large amounts, there are reasons to thoroughly assess the risks of these NPs. READ MORE
