  1. 16. Effects of surface roughness on spillway flow behaviors

    University essay from Uppsala universitet/Nanoteknologi och funktionella material

    Author : Oday Asalya; Joar Fjällborg; [2023]
    Keywords : CFD; ansys fluent; roughness height; ytråhet;

    Abstract : This thesis examines the impact of spillway surface roughness on discharge capacity determination in hydraulic models. The study combines physical hydraulic modeling in a laboratory with Computational Fluid Dynamics (CFD) modeling using Fluent. READ MORE

  3. 17. Evaluating the pressure pulse in a flexographic printing press : Linking process parameters to specific pulse shapes

    University essay from KTH/Hållfasthetslära

    Author : Anton Hedström; [2023]
    Keywords : Flexography; printing; mottle; dot-gain; pressure; contact; Flexografi; tryck; flammighet; punktförstoring; tryckpuls; kontakt;

    Abstract : In the printing industry quality is key, this is because a product is printed for a better appearance or to convey information. If the packaging for a product looks bad customers will get a bad first impression of the product. The quality of the print can be affected by many different factors. READ MORE

  4. 18. Mouthfeel Assessment of Tetra Pak Paper Straws: Exploring the Correlation between Instrumental Measurements and Sensory Evaluation

    University essay from Lunds universitet/Förpackningslogistik

    Author : Natchaya Hanprerakriengkrai; [2023]
    Keywords : mouthfeel; paper straws; correlations; instrumental measurement; sensory evaluation; Technology and Engineering;

    Abstract : The implementation of the Single-Use Plastics Directive has gained significant attention due to the detrimental impacts of plastic pollution, leading to the transition from plastic straws to paper straws for Tetra Pak’s portion-size carton packages. However, the acceptance of paper straws could be hindered by negative mouthfeel perceptions, which customers find the difficulties to accurately describe them. READ MORE

  5. 19. Development of thick GaN and AlGaN drift layers for vertical power devices

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Andri Dhora; [2023]
    Keywords : Technology and Engineering;

    Abstract : High-quality, thick III-nitride epitaxial drift layers with controlled doping are needed for next-generation highly efficient vertical power devices for a smart grid applications and electrification of mobility. Achieving desirable material properties, such as low background impurity concentrations and reduced dislocation densities in combination with high growth rates, necessary for practical application present a challenge.
