1. 1. Hydrogen application of ball valve : An ERIKS case study

   University essay from KTH/Produktionsutveckling

   Author : Lucas Snijder; [2023]
   Keywords : Hydrogen; Ballvalves; EPDM; O-ring;

   Abstract : This thesis investigates the hydrogen application of ball valves. The approach taken was that of a gap analysis where the current situation at ball valve manufacturer ERIKS is considered as a starting point and the desired situation is a ball valve for hydrogen applications.

   Author : Diana Cristina Culincu; [2023]
   Keywords : Augmented Reality; Electric Vehicle Batteries; Lithium-Ion Batteries; Battery Dismantling; Battery Disassembly; Battery Recycling; Photogrammetry; 3D modelling; 3D Reconstruction; Vuforia; Unity; Blender; Figma; Polycam; Sustainability; Förstärkt verklighet; Batterier för elektriska fordon; Litiumjonbatterier; Batteriavmontering; Batteriuppdelning; Batteriåtervinning; Fotogrammetri; 3Dmodellering; 3D-rekonstruktion; Vuforia; Unity; Blender; Figma; Polycam; Hållbarhet;

   Abstract : The increasing adoption of electric vehicles (EVs) brings forth the challenge of effectively managing the second-life and end-of-life cycles for lithium-ion batteries. Augmented Reality (AR) offers a promising solution to sustainably and efficiently dismantle these batteries. READ MORE

4. 3. 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.

5. 4. Development of a Design Tool in CAD for Fused Deposition Modelled Coolant Nozzles in Grinding : Design automation of coolant nozzles

   University essay from Linköpings universitet/Produktrealisering

   Author : Joachim Neguembor; [2022]
   Keywords : Design Automation; Fused Deposition Modelling; DOE; Grinding Coolant; Grinding Process; Coolant Supply in Grinding; Design of Experiment; Surrogate Model Optimization; Coolant Nozzle; Design Automering; Slipande Bearbetning; Kylvätskemunstycke;

   Abstract : This thesis covers the process of automating the design of coolant nozzles used for cylindrical grinding. Coolant nozzles are used to supply coolant, an oil and water mixture used to cool the metal workpiece and lubricate the grinding wheel. In the automotive industry, grinding is used to reduce the surface roughness of the workpiece. READ MORE

6. 5. Linear Impact of Bicycle Helmet – Experimental Testing and FE-modelling

   University essay from KTH/Hållfasthetslära

   Author : Ludvig Dahlin; Ebba Larsson Regnström; [2022]
   Keywords : FEM; Finite element method; bicycle helmet; impact modelling; solid mechanics; FEM; Finita element-metoden; cykelhjälm; islagsmodellering; hållfasthetslära;

   Abstract : The aim with this master thesis was to set up a FE-simulation of an impact test of a bike helmet in LS-DYNA that correlates well with the peak acceleration score of a real life impact test. Furthermore, a parametric study has been performed in LS DYNA to investigate the robustness of the model, as well as to see which parameters have a great influence on the peak acceleration score.
