1. 11. Hydraulic modelling at Finsjö Övre hydropower plant : Study for evaluation of a fishway's attractiveness

   Master-uppsats, Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Författare :Eddie Blomström; [2022]
   Nyckelord :fishway; flow; hydraulics; HEC-RAS;

   Sammanfattning : In connection with the government’s approval on the proposed national plan (NAP) in 2019, it has become highly topical to find solutions problems regarding fish migration in Swedish watercourses. At Finsjö Övre hydropower plant in Emån, a new type of fishway is planned to be installed and evaluated starting at the end of 2022. LÄS MER

3. 12. Chemical Kinetic Modeling of the Combustion of NH3/H2 and NH3/syngas Fuel Mixtures Using a Large Amount of Experimental Data

   Master-uppsats, Lunds universitet/Kemiska institutionen

   Författare :Andras Szanthoffer; [2022]
   Nyckelord :Ammonia combustion; Detailed chemical kinetic mechanisms; Quantitative mechanism comparison; Local sensitivity analysis; Chemical Physics; Chemistry;

   Sammanfattning : Nowadays, due to the global climate change, it is extremely important to find alternative fuels to reduce the utilization of fossil fuels and the emission of air pollutants such as carbon dioxide (CO2), hydrocarbon pollutants, and soot. Ammonia (NH3) is a promising carbon free fuel candidate that can store and transport renewable hydrogen (H2) energy. LÄS MER

4. 13. Groundwater modeling of Krycklan catchment and evaluation of the groundwater discharge distribution

   Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

   Författare :Sandra Edström; [2022]
   Nyckelord :groundwater modelling; groundwater flow; Krycklan catchment; topography-controlled groundwater surface; evapotranspiration; groundwater discharge; groundwater recharge; grundvattenmodellering; grundvattenflöde; Krycklan avrinningsområde; topografi-kontrollerad grundvattenyta; evapotranspiration; grundvattenutflöde; grundvatteninfiltration;

   Sammanfattning : This thesis aimed to evaluate the groundwater discharge distribution in the Krycklan catchment by developing a groundwater flow model using COMSOL Multiphysics and assuming a topography- controlled groundwater surface. Previous research has shown that the groundwater surface can be modeled as a subdued replica of the topography in humid climate regions where the permeability of the subsurface is low and where the groundwater surface is shallow.

5. 14. Experimental optimization and analysis of drying in ifrasound dryer

   Master-uppsats, KTH/Maskinkonstruktion (Inst.)

   Författare :Shreeja-Sivaranjani Natarajan; [2022]
   Nyckelord :Infasound technology; Wheat drying and storage; Drying method; Simulation of drying; Infasound-teknik; Torkning och lagring av vete; Torkningsmetod; Simulering av torkning;

   Sammanfattning : In the agricultural industries drying plays a major role as its very important for grain storage. The selection of the dryer and the method used for drying should be chosen wisely considering the product to be dried with its other factors. LÄS MER

7. 15. Multidisciplinary Modelling of Water Piston Oscillations in Wave Energy Converters : Assessment of Flow Resistance Through CFD Modelling with Fluid Structure Interactions

   Master-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

   Författare :Linnéa Tebelius; [2022]
   Nyckelord :Fluid Mechanics; Point Absorber; CFD; WEC; Waves4Power; Strömnigsmekanik; Point Absorber; CFD; WEC; Waves4Power;

   Sammanfattning : As the world’s need for electricity increases, so does its demand for sustainable energy with low to no greenhouse gas emissions. One of these renewable sources of energy is the Ocean which is one of the world’s largest and most predictable energy source, where the extraction of energy can be from waves or tidal current, with zero greenhouse gas emissions during production.
