  1. 1. Design of Experiment Based on Full Factorial CFD Spray Modelling

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Olle Faritzon; [2023]
    Nyckelord :CFD; spray; liquid; injection; DoE; Design of Experiment; fuel spray; Propane; LPG; OpenFOAM; Experiment; Fluid dynamics; maritime shipping; engine; Technology and Engineering;

    Sammanfattning : Design of experiment is a powerful tool that can reduce the amount of physical testing needed to save resources, time and money. A CFD-setup was constructed in OpenFOAM-8, simulating injection of liquid propane with a standard multi-hole injector. The model was then validated against experimental results. LÄS MER

  3. 2. Early Stage Design of a Prefilmer at Siemens Energy : Numerical and Experimental Methodology

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Jean-Pierre Hamzo; [2023]
    Nyckelord :CFD; gas-turbine; computational fluid dynamics; atomizer; prefilmer; RANS; LES; multi-phase; experimental; numerical; atomization; spray characteristics; drop breakup; liquid fuels; liquid films;

    Sammanfattning : Design of atomizers for gas-turbine purposes are an important ordeal. The per-formance of the atomizer directly impacts the efficiency of the gas-turbine, andconsequently, the energy extracted from the turbine. Furthermore, the design ofthe atomizer can have an impact on reducing toxic emissions. LÄS MER

  4. 3. Development of HVAC simulations for truck cabins using OpenFOAM

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Junaid Haider; [2023]
    Nyckelord :Computational Fluid Dynamics; OpenFOAM; Conjugate Heat Transfer; chtMultiRegionFoam;

    Sammanfattning : In regions with cold climates, a layer of ice often forms on vehicle windshields, whichobstructs the driver’s view. To address this issue, vehicles are equipped with internal defrosters. However, at Scania, the evaluation of defroster design performancecurrently relies on time-consuming and costly physical testing. LÄS MER

  5. 4. Aeroengine transients in altitude test facility

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Baptiste VILLENEUVE; [2022]
    Nyckelord :;

    Sammanfattning : Altitude test facilities offer a safe and reliable way to perform a wide variety of tests on aircraft engine. Among them, aeroengine transients represent a necessary step in the certification and qualification of engines. LÄS MER

  7. 5. CFD investigation of Plate Channels

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Anton Johannesson; [2022]
    Nyckelord :Plate Heat Exchanger; Turbulence modelling; Generalized k-omega; GEKO; CFD; Computational Fluid Dynamics; Technology and Engineering;

    Sammanfattning : Alfa Laval has a wide product range for plate heat exchangers that can be applied in most industries. The constant development of new and old heat exchangers drive the need for new and efficient methods that can reliably be used in the development process. LÄS MER
