1. 1. Investigation of coarse-grid CFD approach for nuclear engineering application

   University essay from KTH/Fysik

   Author : Michela Casarella; [2023]
   Keywords : Thermal-hydraulics; Nuclear reactor; CFD; Sub-channel; Coarse-grid; Turbulence; Pressure drop; Termisk-hydraulik; kärnreaktor; CFD; underkanal; grovkornigt nät; turbulens; tryckfall;

   Abstract : In this thesis, an innovative coarse grid CFD approach is developed that aims toexploit the capabilities of sub-channel codes and CFD methods while overcoming theirlimitations. In the approach, a very coarse mesh is implemented in the CFD softwareOpenFOAM and a new wall treatment, based on the traditional concept of the wallfunction, is applied to the wall boundary conditions of the domain to take into accountthe low resolution of the grid which does not allow to effectively capture the effect of thesolid walls on the thermo-hydraulics of the flow.

3. 2. New process for leak detection in truck pneumatic systems during production using an ultrasound camera

   University essay from Uppsala universitet/Industriell teknik

   Author : Henrik Gustafsson; Malva von Schenck; [2023]
   Keywords : industry; leak detection; leak positioning; pneumatic system; pressure drop test; production; quality assurance; ultrasound camera;

   Abstract : The process of producing compressed air in the industry today is highly energy inefficient. Up to 75 % of the energy spent on producing compressed air to the compressed air systems (CASs) is wasted. Out of the produced air, 24 % is wasted due to air leaks. READ MORE

4. 3. Influence of coal particle sizes on the mechanical strength of iron-carbon briquettes : With focus on steelmaking applications

   University essay from KTH/Materialvetenskap

   Author : Daniel Zaharije Hodgson; Efe Karadag; Maxime Pierre Jean-Claude Saillen; [2022]
   Keywords : ;

   Abstract : Replacing fossil carbon materials with renewable biocarbon is one way to reduce the net carbon dioxide emissions of the iron and steelmaking industry. Carburization is an important application in the electric arc furnace (EAF), and is mostly achieved by adding fossil-based carbon materials into the melt today. READ MORE

5. 4. Construction and Validation of a Lab-scaleBorehole Thermal Energy Storage Model

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Haoyang Dong; [2022]
   Keywords : borehole heat exchanger; lab-scale model; experimental construction; experiment test; validation; borrhålsvärmeväxlare; labbmodell; experimentell konstruktion; experimenttest; validering;

   Abstract : Borehole heat exchangers are widely used in heat pumps of residential buildings and industrialsystems. It is known as one of the most energy ecient technologies which provides heatingand cooling by using sustainable geothermal energy. The life time of borehole heat exchangerslasts more than 50 years which is longer than combustion boilers. READ MORE

6. 5. CFD investigation of Plate Channels

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Anton Johannesson; [2022]
   Keywords : Plate Heat Exchanger; Turbulence modelling; Generalized k-omega; GEKO; CFD; Computational Fluid Dynamics; Technology and Engineering;

   Abstract : Alfa Laval has a wide product range for plate heat exchangers that can be applied in most industries. The constant development of new and old heat exchangers drive the need for new and efficient methods that can reliably be used in the development process. READ MORE
