1. SOFC Modeling from Micro- to Macroscale: Transport Processes and Chemical Reactions
Abstract : The purpose of this work is to investigate the interaction between transport processes and chemical reactions, with special emphasis on modeling mass transport by the Lattice Boltzmann method (LBM) at microscale of the anode of a solid oxide fuel cell (SOFC). In order to improve the performance of an SOFC, it is important to determine the microstructural effect embedded within the physical and chemical processes, which usually are modeled macroscopically.

2. Diffusion of large molecules in steam-exploded wood
Abstract : The diffusion of large molecules in wood pre-treated with steam explosion is important to understand in the context of the materials biorefinery. Steam explosion is a pretreatment method used to both open up the internal structure of wood and increase the accessibility of the cell walls of the wood with the use of high-pressure steam, and it is considered an energy-efficient method.

3. On Microstructural Analysis of Porous Media Existing in Fuel Cells Using the Lattice Boltzmann Method
Abstract : This Licentiate thesis aims to gain understanding related to the fluid behavior in porous media existent in fuel cells (FCs) at microscale. In order to achieve this; the widely used methodology for solving problems in porous media has been applied, the Lattice Boltzmann Method (LBM). READ MORE

4. Efficient Large-eddy Simulation for Wind Energy Applications
Abstract : Modelling the interaction of wind turbines with the ambient flow is essential for almost all technical aspects of wind energy exploitation. Large-eddy simulation (LES) is the most detailed approach feasible to model this complex interaction of wind turbines with the atmospheric boundary layer and the wakes of upstream turbines. READ MORE

5. Transitional flow in ordered porous media
Abstract : Porous media, here defined as any permeable structure allowing a fluid to flow through, are relevant to a multitude of engineering applications and natural processes. The observed macroscopic properties of the porous media such as mixing, heat transfer and apparent permeability are properties which are affected by the flow and especially the type of flow, or flow region.
