1. 16. 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

3. 17. Verification of the fluid dynamics modules of the multiphysics simulation framework MOOSE : A work to test a candidate software for molten salt reactor analysis

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Erik Gustafsson; [2022]
   Keywords : molten salt reactor MSR ; small modular reactor SMR ; computational fluid dynamics CFD ; multiphysics; MOOSE;

   Abstract : This is a report of a verification study of the multiphysics simulation framework MOOSE which was preformed at the company Seaborg Technologies. In the process of designing molten salt reactors there is a special need of making credible multiphysics simulations since the fuel is in motion. READ MORE

4. 18. Fluid flow features in swirl injectors for ethanol fueled rocket : - Analysis using computational fluid dynamics

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Emil Vejlens; Dylan De Jourday; [2022]
   Keywords : Fluid Mechanics; Rocket Science; Fuel injectors; Computational Fluid Dynamics; Swirling Flows; Fuel Mixing;

   Abstract : A swirl injector for a rocket engine being developed by \emph{AESIR} (Association of EngineeringStudents in Rocketry) was simulated with different geometric parameters. The swirl injector is usedto atomize the ethanol used as fuel and to create a spray that mixes well with the oxidizer withinthe combustion chamber. READ MORE

5. 19. Wood and moisture-induced strains in a large deformation setting in 3D

   University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

   Author : Fredrik Ström; Anwar Obeido; [2022]
   Keywords : Total Lagrangian; Finite element method; Large deformation theory; Deformation gradient decomposition; Moisture-induced strains; Hygroscopic; Orthotropic.;

   Abstract : Many studies have previously been done on moisture-induced strains in wood. An in- finitesimal/engineering strain model has been used for most of these studies, which is often an accurate approximation for small rotations. However, if large deformations oc- cur, then fictive strains are obtained resulting from the simplified engineering strain. READ MORE

6. 20. The Investigation and Modeling of the interaction between Paperboard Clippings in a Pipe Flow

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Lea Christierson; [2021]
   Keywords : Fluid-structure interaction; paperboard material modeling; transient pipe flow; overset mesh; image analysis; Technology and Engineering;

   Abstract : In the manufacturing process of Tetra Pak packages, holes are cut out of the paperboard for straws and caps. The left-over paperboard clippings, called confetti, need to be evacu- ated from the machine. However, this evacuation process has proven to cause problems due to jams arising as the confetti get stuck in joints and along the pipe walls. READ MORE
