1. 6. CFD Simulation of Fluid Flow During Laser Metal Wire Deposition using OpenFOAM : 3D printing

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Jennifer Lundkvist; [2019]
   Nyckelord :;

   Sammanfattning : The focus of this work was to simulate the fluid flow within a melt pool geometry, during an additive manufacturing process, implementing the CFD software OpenFOAM version 1806. Two separate models were created and run during this work, the first using a temperature mapping from a finite element (FE) model and the second being a free-standing model with Gaussian distributed laser beam striking down on the top surface.

3. 7. Design of Reliable Lightweight Cast Components : An Optimization Driven Design Appraoch

   Master-uppsats, KTH/Maskinkonstruktion (Avd.)

   Författare :Rohan Kulkarni; [2018]
   Nyckelord :Topology Optimization; Solidification Simulation; Cast Components; Early Stage Castability Evaluation; Topologioptimering; Simulering av stelning; Gjutna Komponenter; utvärdering av gjutbarhet;

   Sammanfattning : The present-day automotive industry is striving to design lightweight components by optimizing the design for minimization of weight. The topology optimization is used widely for the design of lightweight components. The casting process is time and cost effective for mass production and widely adopted within the automotive industry. LÄS MER

4. 8. Dilatometry Study of a High-Chromium Cast Iron

   Master-uppsats, KTH/Hållfasthetslära (Avd.)

   Författare :Benjamin Solem; [2018]
   Nyckelord :;

   Sammanfattning : High-chromium cast irons are used in certain applications where the demand on abrasion resistance is high. Such applications can be found in the milling industry and in pumps for transport of abrasive particles in liquid suspension. Soft annealed high-chromium cast iron containing 2.6 % C and 24. LÄS MER

5. 9. Numerical Analysis ofLatent Thermal Energy Storage in a Cavity

   Kandidat-uppsats, KTH/Energiteknik

   Författare :Robert Olrog; [2017]
   Nyckelord :;

   Sammanfattning : Latent Thermal Energy Storage (LTES) has drawn attention because the technology is a simple and cost-efficient method to store large amounts of energy. Latent energy is either stored or released when the material inside the LTES undergoes phase-change. LÄS MER

7. 10. Numerical modelling of centrifugal casting process

   Master-uppsats, KTH/Materialvetenskap

   Författare :Jun Yin; [2016]
   Nyckelord :mathematical modeling; centrifugal casting; funnel; flow behavior; flow patterns;

   Sammanfattning : The centrifugal casting process is a common method for manufacturing the tubes, etc. Due to its high temperature and invisible mold, it is really difficult to know the mechanism of molten steel inside the mold. LÄS MER
