  1. 1. A Life on the Ocean Wave - Exploring the interaction between the crew and their adaption to the development of the work situation on board Swedish merchant ships

    Author : Monica Lundh; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; engine room; evacuation; work environment; Keywords: Automation; role conflict; ships; stress; engine officers;

    Abstract : ABSTRACTWorking on board merchant ships implies being a part of an isolated context in a multi-cultural arena and spending a lot of time away from family and friends. The shipping industry has during the latest decades undergone major changes due to technical development, automation and increased requirements for profitability and competitiveness. READ MORE

  2. 2. Development of Dual-broadband Rotational CARS for Combustion Diagnostics

    Author : Joakim Bood; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; N2; O2; C2H2; Dimethyl Ether DME ; High pressure; Stray light filtering; multi-point CARS; CARS; Temperature; Engine knock; Physics; Fysik; Fysicumarkivet A:2000:Bood;

    Abstract : The present thesis concerns development and application of dual-broadband rotational coherent anti-Stokes Raman spectroscopy (DB-RCARS) for temperature and species concentration measurements in combustion processes. Both fundamental development of the technique, including experimental as well as modelling results, and measurements in practical combustion devices were conducted. READ MORE

  3. 3. Experimental Studies of Primary Break-up of Diesel Engine Fuel Injector Sprays

    Author : Zachary Falgout; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Water sprays; Sprays; Turbulence; Transparent injectors; Diesel engines; Cavitation; Primary break-up; Orifice flow; Multiphase flows; Transcritical fluids;

    Abstract : This thesis will focus on experimental studies of primary breakup of pressure-atomized sprays. The industrial application that this thesis will address is fuel sprays in modern Diesel engines, and so the focus will be sprays emitting into relatively slow-moving, high pressure, high-temperature gases.

  4. 4. Deformation and Fatigue Behaviour of Aluminium Alloys for High Specific Power IC Engine Applications

    Author : Elanghovan Natesan; Chalmers University of Technology; []
    Keywords : cylinder head; fatigue; thermo-mechanical fatigue; aluminium; ageing; A356; constitutive models; mechanical behaviour;

    Abstract : The development towards higher specific power and lower displacement engines in recent years has placed increasingly high thermal loads on the internal combustion engine materials. Further, the advent of hybrid power trains placing higher demands on quick starts and a rapid approach to maximum power necessitates the automotive industry to move towards a more robust computational thermo-mechanical fatigue life prediction methodology to develop reliable engines and reduce developmental costs.

  5. 5. Closed-Loop Combustion Control of a Multi Cylinder HCCI Engine using Variable Compression Ratio and Fast Thermal Management

    Author : Göran Haraldsson; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CR; Motorer; framdrivningssystem; Motors and propulsion systems; Teknik; Technological sciences; Closed-Loop Combustion Control; CLCC; Multi cylinder; HCCI; Black box; System identification; State feedback; PID; LQG; Fast Thermal Management; FTM; VCR Variable Compression Ratio;

    Abstract : The current Spark Ignited (SI) engine equipped with three-way catalyst offers low emissions, but has low efficiency at part load, which results in unnecessarily high CO2 emissions. The Compression Ignited (CI) engines have higher efficiency and hence lower CO2 emissions, but suffer from higher Nitrogen Oxide (NOx) and Particulate Matter (PM) emissions, and no three-way catalyst can be used.
