21. Modelling of turbulent gas-particle flow
Abstract : An Eulerian-Eulerian model for dilute gas-particle turbulent flows is developed for engineering applications. The aim is to understand the effect of particles on turbulent flows. The model is implemented in a finite element code which is used to perform numerical simulations. READ MORE

22. Image-based numerical modelling of heterogeneous materials
Abstract : In science there has always been a desire to visualise the invisible. Since the discovery of X-rays in 1895, imaging research has made remarkable progress. Nowadays, state-of-the-art technology allows to visualise the micro-structure of objects in three dimensions. However, merely visualising the structure is often insufficient. READ MORE

23. Numerical Modelling and Mechanical Studies on a Point Absorber Type Wave Energy Converter
Abstract : Oceans cover two thirds of the Earth’s surface and the energy potential of ocean waves as a renewable energy source is huge. It would therefore be a tremendous achievement if the vast mechanical energy in waves was converted into a form of energy that could be used successfully by society. READ MORE

24. Groundwater Recharge in Crystalline Bedrock : Processes, Estimation, and Modelling
Abstract : Kunskap om grundvattenbildningen är nödvändig för att man ska kunna förutsäga konsekvenserna av grundvattenuttag och underjordsbyggande. Grundvattenbildningen i berggrunden är dock svår att uppskatta. READ MORE

25. Unsteady Numerical Simulations and Reduced-Order Modelling of Flows around Vehicles
Abstract : In this thesis several simulations have been carried out aimed at improving the knowledge of vehicle aerodynamics and improving the flow around vehicles with respect to theaerodynamic drag. Five flows around different simplified vehicle models have been considered in five appended publications. READ MORE
