1. 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

2. Experimental study of a Volatiles Distributor for Improving the Cross-sectional Gas Distribution in Fluidized Beds
Abstract : Chemical looping combustion (CLC) is a promising carbon capture technology due to its inherent CO2 separation. Significant progress has been made in CLC of solid fuels in recent years. READ MORE

3. Large Eddy Simulation of Complex Turbulent Flows
Abstract : This thesis concerns the Large Eddy Simulation methodology and its application to predict complex turbulent flows at high Reynolds numbers, and at times also with high Mach numbers. The meaning of the word ?complex? refers both to the presence of complex flow phenomena and the, often, complex geometry of man-made devices restricting the flow. READ MORE

4. Numerical study of dynamics of mass-emitting particles in multi-phase flow
Abstract : Suspended particles can be found in wide range of industrial applications such as food industry, mining industry and energy conversion processes. Depending on flow cases which particles are involved, different dynamics and motions are expected from suspended particles. READ MORE

5. Fluidized Bed Operating Parameters and Eulerian Erosion Models
Abstract : A numerical two-fluid code, Gemini 2D, was adapted to study gas-solid fluidization in arbitrary 2D domains. The code was also used to study fluid dynamic mechanisms of dense particle flow that cause ductile and brittle erosion of solids. READ MORE
