1. Modelling of Moving Contact Lines in Two-Phase Flows
Abstract : Moving contact line problems appear in many natural and industrial processes. A contact line is formed where the interface between two immiscible fluids meets a solid wall. Examples from everyday life include raindrops falling on a window and water bugs resting on water surfaces. READ MORE

2. A Numerical Study of the Fluid Dynamics of Bubbling Fluidized Beds
Abstract : The two-fluid model was evaluated as a tool for predicting local flow behaviour in bubbling fluidized beds. A review is given of the two-fluid model approach for simulation of the flow in bubbling fluidized beds. READ MORE

3. Numerical Modelling of Subcooled Nucleate Boiling for Thermal Management Solutions Using OpenFOAM
Abstract : Two-phase cooling solutions employing subcooled nucleate boiling flows e.g. thermosyphons, have gained a special interest during the last few decades. This interest stems from their enhanced ability to remove extremely high heat fluxes, while keeping a uniform surface temperature. READ MORE

4. Computational Techniques for Coupled Flow-Transport Problems
Abstract : This thesis presents numerical techniques for solving problems of incompressible flow coupled to scalar transport equations using finite element discretizations in space. The two applications considered in this thesis are multi-phase flow, modeled by level set or phase field methods, and planetary mantle convection based on the Boussinesq approximation. READ MORE

5. Modelling and Simulation of Turbulent Gas-Solid Flows applied to Fluidization
Abstract : Modelling of gas-solid suspensions has been studied with emphasis on suitable closure laws. A study of characteristic time scales and energy dissipation mechanisms is made for the case of a simple shear flow. Applications of the modelling are presented in the form of simulation and validation of experiments in fluidized beds. READ MORE
