2. 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 tekniska högskola; []
   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

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

   Author : Joakim Bood; Förbränningsfysik; []
   Keywords : 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

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

   Author : Zachary Falgout; Chalmers tekniska högskola; []
   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.

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

   Author : Elanghovan Natesan; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cylinder head; aluminium; constitutive models; thermo-mechanical fatigue; fatigue; ageing; mechanical behaviour; A356;

   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.

7. 5. Advancing the understanding of pilot ignition in dual fuel engines : Experimental and conceptual studies

   Author : Menno Merts; Förbränningsmotorer; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combustion engines; Dual fuel; RCCI; Pilot injection; renewable fuels; Conceptual model; LTC; Heavy duty; Marine; Start of combustion; Optical engine research;

   Abstract : The energy transition is looking for new technologies to reduce CO2 emissions. One of the promising options is the dual fuel engine. In this concept, based on a diesel engine, a small pilot diesel injection is used to ignite a second fuel. READ MORE
