  4. 7. In-Nozzle Flow and Primary Breakup Investigations of Marine Two-Stroke Diesel Engine Injectors

    Author : Reto Balz; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; in-nozzle flow; fuel injection; primary breakup; cavitation;

    Abstract : This thesis will focus on the experimental studies of in-nozzle flow and primary breakup of pressure-atomized fuel sprays as used in large marine two-stroke Diesel engines. To further increase the efficiency of large marine two-stroke Diesel engines, a better understanding of the fuel spray atomization process is necessary. READ MORE

  5. 8. Stiffness of reverse channel connections at room and elevated temperatures

    Author : Tim Heistermann; Darko Beg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Abstract : A frame structure exposed to fire undergoes two types of changes due to the resulting temperature fields. The first is the thermal expansion of the structural members and the second is the degradation of the material strength and stiffness as temperature rises. READ MORE

  6. 9. Real Time Drag Minimization

    Author : Marianne Jacobsen; Ulf Ringertz; Anders Forsgren; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aeronautics; optimization; experimental verification; Vehicle engineering; Farkostteknik;

    Abstract : This thesis focuses on the use of multiple redundant control surfaces to increase performance during flight. There is no clear-cut definition of performance. It may differ between applications, but here, the amount of drag for a given flight condition is used. READ MORE

  7. 10. Load carrying capacity of bridges : three case studies of bridges in northern Sweden where probabilistic methods have been used to study effects of monitoring and strengthening

    Author : Anders Stenlund; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : Probabilistic methods are presented for the assessment of bridges. Load carrying capacity calculations and evaluations of strengthening methods are carried out for three road bridges in northern Sweden: 1) The E4-bridge over Pite River - A four span steel beam bridge with a concrete deck built in 1969.
