  1. 1. Simulation based optimizing of fog mesh structures for enhanced fog collection

    University essay from KTH/Teknisk mekanik

    Author : Jiawei Miao; [2022]
    Keywords : ;

    Abstract : Water scarcity has been an increasing problem in many places around the world. According to the World Resources Institute, in 2019 nearly 2.6 billion people which takes a third of the world's population live in the area with 'high water scarcity', with 1.7 billion people in 17 countries living under 'extreme water scarcity'.

  3. 2. Wading Simulations of Complete Heavy-Duty Vehicles

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Emma Samuelsson; Sofie Benzler; [2022]
    Keywords : CFD; Volume of Fluid; Wading; Heavy-Duty Vehicles; STAR-CCM ;

    Abstract : Wading is the phenomenon where a vehicle drives through water with a relatively deep water level. Sincea large portion of the vehicle is submerged in water it can affect the driveability and function of individualcomponents. READ MORE

  4. 3. Multidisciplinary Modelling of Water Piston Oscillations in Wave Energy Converters : Assessment of Flow Resistance Through CFD Modelling with Fluid Structure Interactions

    University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Author : Linnéa Tebelius; [2022]
    Keywords : Fluid Mechanics; Point Absorber; CFD; WEC; Waves4Power; Strömnigsmekanik; Point Absorber; CFD; WEC; Waves4Power;

    Abstract : As the world’s need for electricity increases, so does its demand for sustainable energy with low to no greenhouse gas emissions. One of these renewable sources of energy is the Ocean which is one of the world’s largest and most predictable energy source, where the extraction of energy can be from waves or tidal current, with zero greenhouse gas emissions during production.

  5. 4. Master’s Thesis Project : Fibre-based preconditioner for granular matter simulation

    University essay from Umeå universitet/Institutionen för datavetenskap

    Author : Henrik Despaigne; [2022]
    Keywords : ;

    Abstract : Simulating granular media at large scales is hard to do because of ill-conditioning of the associated linear systems and the ineffectiveness of available iterative methods. One common way to improve iterative methods is to use a preconditioner which involves finding a good approximation of a linear system A. READ MORE

  6. 5. An Overview of State-of-the-art Hydraulic Conductivity Measurements in Coarse Grained Materials

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Jakob Andrén; [2021]
    Keywords : hydraulic conductivity; permeability; embankment dam; coarse grained; flow regime; hydraulisk konduktivitetsmätning; permeabilitet; fyllnadsdamm; grovkorniga material; flödesregim;

    Abstract : Embankment dams are made from soil materials of varying sizes and widely used all over the world.When constructing these, knowing the hydraulic conductivity (K) of the soil materials is a keyparameter in order to construct safe embankment dams. A knowledge gap regarding K measurementsin coarse grained soils has been identified. READ MORE
