  1. 16. Evaluation of Coefficient of Friction in Oblique Helmet Impacts: An Experimental and Numerical Study

    University essay from KTH/Hållfasthetslära

    Author : Philip Singh; [2022]
    Keywords : FE model; friction; helmet impact; LS-DYNA; FE-modell; friktion; hjälmislag; LS-DYNA;

    Abstract : The focus of this thesis was to increase the knowledge in the area of "dynamic friction" during oblique helmet impacts, both experimentally and numerically. Physical experiments have been performed with multiple helmets, different angles of the anvil and different surface materials, with results of impact forces from the anvil and accelerations of the head.

  3. 17. 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. 18. Groundwater modeling of Krycklan catchment and evaluation of the groundwater discharge distribution

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Sandra Edström; [2022]
    Keywords : groundwater modelling; groundwater flow; Krycklan catchment; topography-controlled groundwater surface; evapotranspiration; groundwater discharge; groundwater recharge; grundvattenmodellering; grundvattenflöde; Krycklan avrinningsområde; topografi-kontrollerad grundvattenyta; evapotranspiration; grundvattenutflöde; grundvatteninfiltration;

    Abstract : This thesis aimed to evaluate the groundwater discharge distribution in the Krycklan catchment by developing a groundwater flow model using COMSOL Multiphysics and assuming a topography- controlled groundwater surface. Previous research has shown that the groundwater surface can be modeled as a subdued replica of the topography in humid climate regions where the permeability of the subsurface is low and where the groundwater surface is shallow.

  5. 19. 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.

  6. 20. Verification of the fluid dynamics modules of the multiphysics simulation framework MOOSE : A work to test a candidate software for molten salt reactor analysis

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Erik Gustafsson; [2022]
    Keywords : molten salt reactor MSR ; small modular reactor SMR ; computational fluid dynamics CFD ; multiphysics; MOOSE;

    Abstract : This is a report of a verification study of the multiphysics simulation framework MOOSE which was preformed at the company Seaborg Technologies. In the process of designing molten salt reactors there is a special need of making credible multiphysics simulations since the fuel is in motion. READ MORE
