1. Development of an Improved Thermal-Hydraulic Modeling of the Jules Horowitz Reactor
Sammanfattning : The newest European high performance material testing reactor, the Jules Horowitz Reactor, is under construction at CEA Cadarache research center in France. The reactor will support existing and future nuclear reactor technologies, with the first criticality expected at the end of this decade. LÄS MER
2. Fluid dynamics and mass transfer in bubble columns with and without packing
Sammanfattning : Bubble columns are used in the chemical industry to perform gas liquid reactions, like oxidation, hydrogenation and fermentation. The objective of the present thesis was mainly to study the fluid dynamics of semi batch packed bubble columns at both atmospheric and pressurized conditions. LÄS MER
3. On Modeling the Dynamics of Fixed Biofilm Reactors. With focus on nitrifying trickling filters
Sammanfattning : Fixed biofilms, which are matrix-enclosed populations of organisms attached to solid surfaces, are increasingly used in environmental biotechnology processes, such as the treatment of potable water and wastewater. This thesis aims to give some insight into the dynamic modeling of biofilms and fixed biofilm reactors, with a focus on nitrifying trickling filters (NTFs) for the treatment of wastewater. LÄS MER
4. Process Optimization of UV-Based Advanced Oxidation Processes in VOC Removal Applications
Sammanfattning : Air pollution is a major concern in developed countries due to its hazardous health effects. Recent studies by the WHO (World Health Organization) estimate that urban air pollution causes a number of diseases of the respiratory tract and is associated with 150,000 deaths each year. LÄS MER
5. Growth Dynamics of Semiconductor Nanostructures by MOCVD
Sammanfattning : Semiconductors and related low-dimensional nanostructures are extremely important in the modern world. They have been extensively studied and applied in industry/military areas such as ultraviolet optoelectronics, light emitting diodes, quantum-dot photodetectors and lasers. LÄS MER
