1. Turbulent flows over permissive boundaries and porous walls
Sammanfattning : This thesis investigates how in wall-bounded turbulent flows changes to the wall can induce changes in the flow. To this end, we investigate the use of wall boundary conditions meant to mimic the effect of textured surfaces. LÄS MER
2. Mathematical and Experimental Study on Filtration of Solid Inclusions from Molten Aluminium and Steel
Sammanfattning : Aluminum and steel have been the most produced metal and alloy, respectively, for many years. Their extensive use in various industries, their fundamental role in our everyday life, and their excellent recycling characteristics are the major driving forces for development of their production towards more sustainable processes.

3. A multi-resolution approach for modeling flow and solute transport in heterogeneous porous media
Sammanfattning : Subsurface processes are usually characterized by rare field experiments, sparse measurements,multi-resolution interpretations, stochastic description, related uncertainties and computational complexity. Over the last few decades, different computational techniques and strategies have become indispensable tools for flow and solute transport prediction in heterogeneous porousmedia. LÄS MER
4. Dynamics of wood particle pyrolysis applied to gas-solids fluidisation
Sammanfattning : Avhandlingen behandlar matematiska modellerings- och simuleringsaspekter samt resultat rörande pyrolys av stora och små träpartiklar. Avhandlingsarbetet är inriktat på två specifika processer. Den ena är pyrolys av enstaka träpartiklar och den andra är pyrolys av fluidiserade träpartiklar. LÄS MER
