1. 16. Surface Interactions in Powder Injection Moulding

   Författare :Elisabeth Johansson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; surfactants; powder injection moulding PIM ; rheology; steel powder; surface interactions; XPS; SIMS; adsorption; surface composition;

   Sammanfattning : Powder Injection Moulding (PIM) is an attractive technique for producing complex components in large quantities my means of powder technology. The process includes mixing powder with a suitable binder, usually a thermoplastic polymer. Because of the large attractive forces between small particles the powder can be agglomerated in the binder. LÄS MER

3. 17. On Gas Turbine Diagnostics with Emphasis on Combustion Chambers

   Författare :Raik Orbay; Kraftverksteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbulent combustion; PDA; swirl stabilisation; PIV; off-design.; Gas turbine; experimental methods; LDA; atomisation; emission measurements;

   Sammanfattning : The thesis aims to analyse the gas turbine based energy conversion systems with the emphasis on combustion chambers. The investigation is mainly experimental at a component level. The majority of investigations concentrate on gaseous fuel firing. LÄS MER

4. 18. Experimental investigation of flows related to gas turbine combustion

   Författare :Dragan Stankovic; Strömningsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mechanical engineering; combusiton; flameless; jets in cross flow; chemiluminescence; POD; LIF; PIV; Spray; Gas Turbine; single digit NOx; Premixed Combustion; hydraulics; vacuum technology; vibration and acoustic engineering; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik;

   Sammanfattning : The notion of "global warming" has become a major public-domain concept as an environmental threat to our future on earth. Independently of the accuracy of existing prediction of combustion emissions on the climate on earth, the concept of reducing combustion emissions has been an important political driving force in imposing more and more severe restrictions on harmful emissions from combustion.

5. 19. Development of LPP-Burner for Industrial Gas Turbine Application

   Författare :Jonas Holmborn; Strömningsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal engineering; Dry Low Emission DLE ; Lean Partially Premix LPP ; Combustion; Gas Turbine; Burner; applied thermodynamics; Termisk teknik; termodynamik;

   Sammanfattning : This thesis reports the work done in the development of a modified Lean Premix Prevaporised (LPP) burner for the use in Alstom Power Sweden’s industrial gas turbines. Incentive for the development of the modified burner have been the need to increase the flame stability over the operating range for the burner, especially for the liquid fuel but also the gaseous fuel operation.

7. 20. Alcohol Flexible Dual-Fuel Direct Injection Engine

   Författare :Michael Saccullo; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fuel spray; Ethanol; Dual-fuel; Heavy duty engine; Diffusion combustion; Dual-direct injection; E85; Methanol;

   Sammanfattning : Laws concerning emissions from HD internal combustion engines are becoming increasingly stringent in terms of local emissions and emissions concerning global warming such as lowering tailpipe CO2. New engine technologies are needed to satisfy these new requirements and to reduce fossil fuel dependency and increase renewable fuels in the transportation sector. LÄS MER
