  1. 1. CFD investigation of a unit cell inside a Plate Heat Exchanger

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Mattias Ly; [2023]
    Nyckelord :Plate Heat Exchanger; CFD; Computational Fluid Dynamics; LES; Large Eddy Simulation; Periodic; Unit Cell; Technology and Engineering;

    Sammanfattning : A numerical investigation of the unit cell approach has been done to reduce the computational cost for CFD (Computational Fluid Dynamics) of plate heat exchangers (PHE) at Alfa Laval. The reduced cost would enable LES (Large Eddy Simulation) to be done which would give a more detailed and accurate insight into the flow and heat transfer processes of the PHE. LÄS MER

  3. 2. The potential future travelers on the North Bothnia Line : Sävar, Robertsfors and Bureå

    Master-uppsats, Umeå universitet/Institutionen för geografi

    Författare :Johanna Mikkola Bouvin; [2023]
    Nyckelord :North Bothnia Line; Sustainable transport; Sustainable travel; Social sustainability; Socially sustainable travel; Socially sustainable public transport; Transport justice; Transport poverty; Travel mode choice; Travel behavior; Sävar; Robertsfors; Bureå; Norrbotniabanans noder 2;

    Sammanfattning : With a foundation in social sustainability, and with the theoretical framework of transport justice and transport poverty, the aim of this thesis is to create a profile picture of the future potential travelers on the North Bothnia Line in Sävar, Robertsfors and Bureå. Both a quantitative and a qualitative analysis are performed. LÄS MER

  4. 3. Race Car Monitor

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

    Författare :Erik Orrenius; Pontus Rahm; [2022]
    Nyckelord :OBD2; CAN; SAE J1850; KWP2000; Android; ECAD;

    Sammanfattning : To evolve and develop your skills as a driver, it is worthwhile to review and reflect on your last drive at a professional as well as beginners level. The purpose of the project is to create such a system that can be used to record a drive by filming from the dashboard of the car and logging data from the vehicle. LÄS MER

  5. 4. Rural views on the transition from fossil-fuelled cars to electric cars

    Master-uppsats, SLU/Dept. of Urban and Rural Development

    Författare :Matilda Hedelin; [2022]
    Nyckelord :electric cars; fossil fuels; sociotechnical imaginaries; rural development;

    Sammanfattning : This study highlights perspectives considering the transition from fossil-fueled cars to electric cars in the Swedish passenger car fleet. The perspectives origins from semi-structured interviews with six rural residents in Värmland, Sweden, and from examined editorials, news reporting and debate articles in the Swedish newspaper Dagens Nyheter (DN).

  7. 5. Numerical study of a vibroacoustic wave trap for e-vehicles

    Master-uppsats, KTH/Teknisk akustik

    Författare :Antoine Curien; [2022]
    Nyckelord :wheel vibrations; passive vibration control; multiple tuned mass damper; bending mode; numerical optimisation; damping; resonance; robustness; reduction methods; Hjulvibrationer; passiv vibrationsreglering; multi tuned mass damper; böjningsläge; numerisk optimering; dämpning; resonans; robusthet; modale reduktionsmetoder;

    Sammanfattning : The transition from internal combustion engine to battery electric cars is accompanied by a shift on the NVH issues damaging the passenger comfort. The rolling noise generated by the wheels and tyres is in particular characterized by an increasing attention from OEMs and car manufacturers. LÄS MER
