  1. 21. Engine and Gearbox Thermal Management Modeling

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Amaury Arlotto; [2018]
    Keywords : ;

    Abstract : In order to improve the global efficiency of an engine within the French company Groupe PSA, a research axis focuses on gearbox thermalmanagement for a quicker reduction of its own friction losse after a cold start. The principle remains in deriving a little part of the coolant energy towards the gearbox – until now heated by its own internal frictions – as long as the impact on the engine warm-up is low enough for a global final gain.

  3. 22. AA-CAES physical modelling: integration of a 1D TES code and plant performance analysis

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Luca Santo; [2018]
    Keywords : energy storage; balancing; grid; AA-CAES; CAES; peaks; energy scenarios; s-function; simulink; simscape; matlab; C ; TES; thermal energy storage; dumping; demand side management; power systems; turbine; compressor; cavern; CAS; compressed air; heat exchange;

    Abstract : The focus of this thesis work was the development of an approachto couple a previosly existing Thermal Energy Storage (TES) modelwritten in C++ with a Simulink/Simscape plant model to simulate anAdvanced Adiabatic Compressed Air Energy Storage (AA-CAES) plant.After the creation and validation of such tool, the complete modelwas used to run simulations, with the aim of assessing the AA-CAESplant's performance under multiple patterns of charge anddischarge.

  4. 23. Multi-scale modelling of fire in accelerator tunnels: a CERN case study

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Melchior Schepers; [2018]
    Keywords : Multi-scale modelling; CFD; tunnel fires; FDS; CERN; particle accelerator; Technology and Engineering;

    Abstract : Multi-scale modellering is een nieuwe benadering in het modelleren van rook en brand in systemen waarbij de grootte van het domein een meer conventionele volledige 3D modellering onmogelijk maakt. Het domein wordt opgesplitst in een 1D en 3D gedeelte om zo de simulatietijd te verminderen. READ MORE

  5. 24. Development of a 1D to 3D CFD couplingmethodology on an inlet manifold

    University essay from KTH/Mekanik

    Author : Andreas Johansson; [2018]
    Keywords : ;

    Abstract : We investigate the coupling between 3D simulations of the flow in an engine manifold with simplified 1D models of the engine performance. The inlet manifold in an existing 1D engine model is replaced with a more sophisticated CFD manifold simulation. The rest of the 1D system is left untouched. READ MORE

  6. 25. Planet migration in evolving protoplanetary discs

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Linn Eriksson; [2018]
    Keywords : Planets and satellites: formation; Protoplanetary discs: evolution; Planet-disc interactions; Physics and Astronomy;

    Abstract : The rate of migration and accretion onto protoplanets is greatly influenced by the structure of the surrounding protoplanetary disc. This structure changes with time as the disc evolves on a million year timescale, implying that the process of planet formation might look very different depending on when it was initiated. READ MORE
