A thermogravimetric and kinetic study on devolatilization of biomass
(Master thesis, 2018)The pyrolysis characteristics of spruce wood and birch wood, both of two different particle sizes: 0.063-0.1 mm and 0.2-0.3 mm were investigated using thermogravimetric analyzer. The pyrolysis process was subdivided into ... -
Adiabatic compressed air energy storage
(Master thesis, 2015)An increasing amount of intermittent renewable energy sources are being introduced to the European electrical grid. This results in difficulties to maintain and ensure a reliable and steady electricity supply. Energy storage ... -
Design and fabrication of micro-nano enhanced surfaces for controlling Leidenfrost point
(Master thesis, 2016)The technological revolution has driven the need for faster microprocessors. In order to fabricate faster microprocessors the trend has been to increase the amount of transistors and increase the clock speed. Microprocessor ... -
Energy Efficient Drying Systems for the Dried Cured Meat Industry
(Master thesis, 2015)Production of dry-cured meat requires large amounts of energy. To reduce the running costs in the dry-cured meat industry, which are closely related to the energy needs, eight energy systems for drying of meat were simulated ... -
Experimental and numerical kinetic study on charged and excited species in oxyfuel combustion for CO2 capture
(Master thesis, 2016)Within the scope of the work, selected chemical kinetics and combustion issues were investigated. The first part contains a study of high temperature plasma and its po- tential usage as a working fluid in the magnetohydrodynamic ... -
Life cycle assessment of electric power generation by wind turbines containing rare earth magnets
(Master thesis, 2015)Direct-drive permanent magnet generator (DD-PMG) wind turbines are becoming a larger part of the growing offshore wind turbine market. The strong permanent magnets used, the NdFeB magnets, contains neodymium metal. The ... -
Numerical investigation of thermal-hydraulics performance of fin-tube waste heat recovery units
(Master thesis, 2015)The objective of this master thesis is to increase the understanding of fluid flow and heat transfer development across a finned tube heat exchanger with help of Computational Fluid Dynamics (CFD). Three different geometries ... -
Optimization of ORCs for low grade heat recovery: working fluid selection, methodology and applications
(Master thesis, 2017)n this work two different heat sources were considered: geothermal brine at temperatures ranging from 90 to 150°C, and waste heat coming from an aluminum manufacturing plant. A number of 64 pure fluids and 35 mixtures were ... -
Termisk-hydraulisk beregningsverktøy for sjøvannskjølere
(Master thesis, 2016)Formålet med denne oppgaven var å utarbeide en komplett beregningsmodell for beregning av termisk- og hydraulisk ytelse til en ny type varmeveksler kalt Rack Cooler. Denne typen varmeveksler blir brukt til kjøling i marine ... -
Theoretical study of Mechanical Stability of charcoal from biomass resources
(Master thesis, 2017)There is a large potential for lowering CO2 emissions from the metallurgical industry if carbon neutral bio based reductants could replace fossil coke. The inferior mechanical stability of bio based charcoal is one of the ... -
Weight Estimation of Steam Cycle for CO2 Capture System on Offshore Oil and Gas Installation
(Master thesis, 2016)Climate change due to increasing anthropogenic CO2 emissions is a major concern both in Norway, and globally. Greater environmental focus and increased taxes on emitted CO2 have led to corporate efforts on reducing CO2 ...
