1. 11. Laser Scattering for Fast Characterization of Cellulose Filaments

   University essay from KTH/Fiber- och polymerteknologi

   Author : Alexandra Konstantinidou; Saga Holmström; Susanna Hellberg; [2022]
   Keywords : Cellulose nanofibrils; Fibers; Sustainable development; Bio-based material; Characterization; Microscale; Microscopy; Small-angle light scattering; Laser diffraction; Cellulosananofibriller; Fiber; H˚allbar utveckling; Biobaserade material; Karakterisering; Mikroskala; Mikroskopi; Ljusspridning; Laserdiffraktion;

   Abstract : Cellulosananofibriller (CNFs) hör till naturens mest fundamentala byggstenar och förser naturliga material, såsom den yttre cellväggen i trä, med en otrolig styrka och styvhet. Genom att imitera träets arkitektur öppnas möjligheter upp för tillverkning av nya, biobaserade och lättviktiga strukturella material med mekaniska egenskaper som överskrider de för glasfiber, metaller och legeringar.

3. 12. Boundary conditions at left ventricle wall for modelling trabeculae in blood flow simulations

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Lukas Werner; Ellen Leonardsson; [2022]
   Keywords : Trabeculae; CFD; Computational Fluid Dynamics; Hemodynamics; Blood Flow Simulations; Endocardial wall; porous; boundary conditions;

   Abstract : Heart disease is the main cause of death today, and studying causes and treatments are of great interest. Blood flow simulations using computational fluid dynamics shows promise in providing insight into this area. This study builds upon previous work by Larsson et al. and Kronborg et al. READ MORE

4. 13. Similarity assessment of floor plans : Tackling the challenge of how to compare floor plans with each other

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Gustav Lindqvist; [2022]
   Keywords : image analysis; floor plans; pixel algorithms; tesseract; room identification; wall extraction; similarity; booli; bildanalys; planritningar; pixelalgoritmer; tesseract; rumidentifiering; väggextrahering; jämför; booli;

   Abstract : This paper tackles the challenge of how to compare floor plans with each other. A lot of different methods were used to analyze floor plan images, such as different kinds of pixel-based breadth-first search algorithms for finding walls, doors, and windows. READ MORE

5. 14. Design of compact automotive heat exchanger, analysing the effects of RANS models and utilising Additive Manufacturing

   University essay from KTH/Fysik

   Author : Nikhil Srikkanth; Bartosz Brzuchalski; [2022]
   Keywords : Turbulence; Reynolds Averaged Navier-Stokes; KTH Formula Student; metal additive manufacturing; CFD; turbulent kinetic energy; boundary layer;

   Abstract : The analytical modelling of complex turbulent airflow remains one of the great unsolved mysteries of physics, but in this paper two widely used Reynolds Averaged Navier-Stokes models (k-$\epsilon$ and k-$\omega$ SST) are compared while designing a heat exchanger for the KTH Formula Student electric race car. CAD software was used to design lattices for the heat exchanger core and theorise about how to increase heat transfer while also taking into account the utilisation of metal additive manufacturing.

6. 15. Rammed Concrete

   University essay from KTH/Arkitektur

   Author : Marvin Palmgren; [2022]
   Keywords : Rammed Concrete; Rammed Earth; Building Technique; Building Method; Material Study;

   Abstract : Rammed Concrete is a material study of an old building technique called rammed concrete and its predecessor rammed earth. Rammed earth is a technique used for constructing foundations, floors, and walls with the use of natural materials. READ MORE
