  1. 1. Development of CAD Models for Large Silencer Platforms Using Design Automation

    University essay from Linköpings universitet/Produktrealisering

    Author : Mahim Kai; Balagangadar Thilakar Arumugam; [2023]
    Keywords : Design Automation; Silencer; CFD; Extraction;

    Abstract : Scania is known as a front-runner in the development of power trains for heavy vehicles, marine, and general industrial applications. As the regulations on emissions for combustion engine vehicles are getting tougher with increasing awareness on sustainable solutions and reducing environmental impact, the goal at Scania is to develop combustion engines to achieve low-pollutant emissions whilst achieving higher efficiency.

  3. 2. CFD investigation of a unit cell inside a Plate Heat Exchanger

    University essay from Lunds universitet/Institutionen för energivetenskaper

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

    Abstract : 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. READ MORE

  4. 3. Design of Experiment Based on Full Factorial CFD Spray Modelling

    University essay from Lunds universitet/Institutionen för energivetenskaper

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

    Abstract : 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. READ MORE

  5. 4. Simulation of Combustion in a Hybrid Rocket Engine

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Oscar Andersson; [2023]
    Keywords : Thesis; Hybrid Rocket Engine; CFD; computational fluid dynamics; combustion;

    Abstract : A numerical investigation on the combustion mechanics of a hybrid rocket engine is performed through unsteady Reynolds-averaged Navier-Stokes simulation. The hybrid rocket engine model is based on an experimental laboratory scale engine design operating on GOX and HDPE as a propellant. READ MORE

  6. 5. A numerical comparison of the thermoacoustics for different equivalence ratios for n-dodecane using LES

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Björn Jarfors; [2023]
    Keywords : Computational Fluid Dynamics; Bluff-body stabilised flames; Large Eddy Simulation; Thermoacoustics; Acoustics; NEUMANN Project; Jet engines; Aero engines; Airplanes; Combustion; Numerics; Technology and Engineering;

    Abstract : Klimatförändringarna påverkar vår värld och det behövs ett mer hållbart samhälle. Flygindustrin är i behov av förändring, men flygmotorer är mycket komplexa och tar tid att utveckla. Termoakustiska instabiliteter har kraften att förstöra en motor, men också att minska miljöpåverkan. READ MORE
