1. Modelling of the gas flow in fluidized beds
University essay from Chalmers tekniska högskola/Institutionen för energi och miljöAbstract : Fluidized bed technology plays an important role in the transition of the current energy system to full sustainability, both as main first choice for thermochemical biomass conversion (which is considered CO2 neutral) and as basis for chemical looping combustion (CLC), which is considered to be the second generation of carbon capture applications, since it allows CO2 capture with no inherent energy penalty.The aim of the work is to formulate and implement a proper description of the gas flow inside a fluidized bed, covering a variety of scales and applications.

2. A Cut Finite Element Method for Partial Differential Equations on Evolving Surfaces
University essay from KTH/Numerisk analys, NAAbstract : This thesis deals with cut finite element methods (CutFEM) for solving partial differential equations (PDEs) on evolving interfaces. Such PDEs arise for example in the study of insoluble surfactants in multiphase flow. In CutFEM, the interface is embedded in a larger mesh which need not respect the geometry of the interface.

3. Numerical Methods for Simulating Separation in a Vacuum Cleaner Cyclone
University essay from KTH/MekanikAbstract : This thesis includes a numerical comparison of different turbulence models and particle models in terms of convergence time and physical accuracy. A cyclone is used as the computational domain. Cyclones are common devices for separating two or more substances. The work is divided into an experimental part and a numerical part. READ MORE

4. Numerical investigation of bubbles in channel flow
University essay from Chalmers tekniska högskola/Institutionen för sjöfart och marin teknikAbstract : This master’s thesis aims to study the numerical methods that can simulate the influence of injection of air bubbles under a ship’s hull. The geometry of the hull is simplified to a flat plate and the analysis is only done in two dimensions. READ MORE

5. Assessment of Volume of fluid Method for high-pressure gasinjection into liquid
University essay from KTH/MekanikAbstract : Carbonated sparkling water has been widely used from ancient age [1]. The original ideacame from natural sparkling water and people believed that taking baths at carbonatedhot springs was good for health and healed their sicknesses. This fact led people to startthinking that sparkling water could have more effective uses. READ MORE
