  3. 2. 1D Simulation of Hydraulic Cam Phaser System Utilized in Heavy Duty Vehicles : An Investigation on Attenuation of Phase Oscillations from Cam Torque Disturbances

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

    Författare :Johan Germundsson; [2023]
    Nyckelord :master thesis; cam phaser; simulation; 1D-simulation; GT-SUITE; GT-ISE; Gamma Technologies; oil aeration; oscillations; heavy-duty; engine; phaser; cam torque; stability; cam phaser system; Scania; Scalia CV;

    Sammanfattning : Cam phasers allow improvements to the efficiency and emissions of internal combustion engines. The usage of hydraulic vane type cam phasers for heavy-duty applications have shown problems with oscillations during testing at Scania CV. To investigate the root cause of the oscillations a detailed 1-d simulation model has been created. LÄS MER

  4. 3. CFD Simulations of Flow Characteristics of a Piano Key Weir Spillway

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :William Sjösten; Victor Vadling; [2020]

    Sammanfattning : Comprehensive rehabilitation projects of dam spillways are made in Sweden, due to stricter dam safety guidelines for their discharge capacity. The Piano Key Weir (PKW) is an innovative design which has proven effective through several renovation projects made in many countries including France. LÄS MER

  5. 4. CFD simulation of particle matter inside an automotive car and the purification efficiency of cabin air purifier

    Master-uppsats, KTH/Hållbara byggnader

    Författare :Sebastian Ljung; [2019]
    Nyckelord :CFD; car cabin; air quality; air flow simulation; CFD; bilkabin; luftkvalitet; luftflödessimulering;

    Sammanfattning : The purpose of this thesis work was to study the airflow patterns and the particle distribution in a generic car cabin in order to evaluate the air quality and find how it can be improved. A 3D CAD model was created using the Solidworks software program and meshed using ICEM CFD software. LÄS MER

  7. 5. Direktljud genom olika friskluftsventiler och dess påverkan på boendekvalitén

    Uppsats för yrkesexamina på grundnivå, Linnéuniversitetet/Institutionen för byggteknik (BY)
