1. 1. Power Reconstruction Uncertainties in European Pressurized Reactor Impact of Partial. Unavailability of Sensors

   University essay from KTH/Fysik

   Author : Matthieu Causse; [2022]
   Keywords : ;

   Abstract : This study is part of a theme related to the physical tests performed on the core of nuclear reactors and particularly the EPR, a new French reactor under construction on the Flamanville site. The peaking factors of this reactor are continuously monitored by an instrumentation located both inside (collectrons) and outside (external fission chambers) the core. READ MORE

3. 2. Methane and Carbon Dioxide Emissions From Three Smallscale Hydropower Stations in South of Sweden

   University essay from Linköpings universitet/Tema Miljöförändring

   Author : Edevardt Johan Danielsen; Alexandra Jonsson Valderrama; [2022]
   Keywords : Hydropower; Reservoir; Freshwater; automated Flux chambers; Emissions; Ebullition; Diffusion; Greenhouse gases; GHGs; Methane; CH4; Carbon dioxide; CO2; Dissolved oxygen; DO; Variability; Spatial; Temporal; Dissolved inorganic carbon.; Vattenkraft; Reservoar; Sötvatten; automatiserade Fluxkammare; Utsläpp; Ebullition; Diffusion; Växthusgaser; GHHs; Metan; CH4; Koldioxid; CO2; Löst syre; DO; Variabilitet; Rumslig; Temporal; Löst oorganiskt kol.;

   Abstract : Over the past decades, evidence show that the anthropogenetic greenhouse gases (GHG) emissions of carbon dioxide (CO₂) and methane (CH₄) are the main drivers behind global warming and are becoming stronger. Globally, hydropower is among the main sources of renewable energy and the popular notion that hydropower electricity is carbon neutral has been under debate as evidence from measurements in different regions of the globe show significant and highly variable carbon emissions from hydropower reservoirs.

4. 3. Greenhouse gas emissions from three large lakes during the autumn 2020

   University essay from Linköpings universitet/Institutionen för tema

   Author : Veronica Bohlin; Anja Anderö Nordqvist; [2021]
   Keywords : methane; carbon dioxide; dissolved inorganic carbon; pCO2; flux chambers; large lakes; methane budget; carbon budget; GHGs; freshwater; spatiotemporal; ebullition; diffusion; autumn; metan; koldioxid; upplöst oorganiskt kol; pCO2; kammarmetod; stora sjöar; metanbudget; koldioxidbudget; växthusgaser; sötvatten; spatiotemporal; ebullition; diffusion; höst;

   Abstract : Methane (CH4) and carbon dioxide (CO2) are two greenhouse gases and main drivers of global climate change. Lakes are known to be a source of CH4 and CO2 to the atmosphere. While the importance of these emissions is clear, their magnitudes and regulation are still uncertain due to the scarcity of flux measurement data from lakes. READ MORE

5. 4. Variability of summer CH4 and CO2 flux rates in and between three large Swedish lakes : A spatio-temporal field study

   University essay from Linköpings universitet/Tema Miljöförändring

   Author : Isak Nilsson; Filip Seifarth; [2020]
   Keywords : Large lakes; Freshwater; Flux chambers; Emissions; Ebullition; Diffusion; Carbon cycle; Carbon budget; Methane budget; Greenhouse gases; GHGs; Methane; CH4; Carbon dioxide; CO2; Variability; Spatial; Temporal; Stora sjöar; sötvatten; flödeskammare; utsläpp; bubblor; diffusion; kolcykel; kolbudget; metanbudget; växthusgaser; metan; CH4; koldioxid; CO2; variabilitet; rumslig; tidsmässig;

   Abstract : Understanding of natural greenhouse gas (GHG) cycles is crucial for making GHG budgets, which work as basis in climate change and global warming policy programs. Lakes as a source for GHG activity have only recently been included in global GHG budgets, and most studies of lake GHG flux rates are conducted on lakes <10 km2, which only comprise roughly half of the global lake area—making data of large lake flux rates scarce.

6. 5. Thermal gas radiation modelling for CFD simulation of rocket thrust chamber

   University essay from KTH/Kraft- och värmeteknologi

   Author : Rejish Lal Johnson Samee Lal; [2019]
   Keywords : Gas radiation; thrust chamber; CFD; heat transfer; Rocflam3; methane; Gasstrålning; tryckkammare; CFD; värmeöverföring; Rocflam3; metan;

   Abstract : Methane and oxygen are a promising propellant combination in future rocket propulsion engines mainly due to its advantages like reusability and cost reduction. In order to have a comprehensive understanding of this propellant combination extensive research work is being done. READ MORE
