  1. 11. Analysis and Applications of Minimum Quantity Lubrication (MQL)

    Författare :Bulent Tasdelen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dry; compressed air; sliding; MQL; temperature; nozzle; oil amount; seizure; tool wear; tool-chip contact surface topography.; contact length;

    Sammanfattning : One of the greatest obstacles to the implementation of MQL is “lack of knowledge” which also limits the expansion of its usage. The presented work aims to take a step toward a better understanding of the mechanisms that occur in MQL assisted machining. LÄS MER

  5. 14. Nozzle design for pulsed water jets : an analytical, numerical and experimental study

    Författare :Rolf Lövgren; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : A study is made of the early time behaviour of pulsed water jets generated by the action of a shock wave moving through a waterfilled nozzle. In particular the influence of nozzle geometry on the exit velocity is examined. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER
