  2. 1. Flow field in a gas turbine burner

    University essay from Luleå tekniska universitet/Maskinteknik/Fluid Mechanics

    Author : Shervin Khayamyan; [2010]
    Keywords : gas turbine; burner; combustion; CFD simulation; BurningVelocity Model BVM ; Flamelet model; spray; primary breakup; secondary breakup; diesel fuel;

    Abstract : This report presents a numerical investigation of diesel fuel spraycombustion in SGT-800 gas turbines with ANSYS CFX 11.0. The gas turbineSGT-800 has thirty burners and each burner has four fuel injectors. In thisthesis just a quarter of one burner is simulated. READ MORE

  4. 2. Laser welding of hardenable steel

    University essay from Luleå tekniska universitet/Maskinteknik/Engineering Materials

    Author : Sinuhé Hernández; [2010]
    Keywords : Laser welding; hardenable; steels; gleeble; induction heat treatment;

    Abstract : In the present work a novel idea based on nucleation and growth applied to an induction heat treatment of a laser welded component is presented. With this new concept, the microstructure and hardness of hardenable steel SS142225 with a thickness of 12 mm are believed to be improved by prolonging the cooling time after laser-welding and decreasing the preheat temperature.

  5. 3. Performance Evaluation Framework for a SIP-based Telecommunication Call Handling System

    University essay from

    Author : NATTANOND SANGVANPHANT; [2009]
    Keywords : ;

    Abstract : Session Initiation Protocol (SIP) has been used for signaling in many Voice over IP(VoIP) applications. Being more cost-effective than conventional circuit-switchedsystems, IP-based telecommunication systems are extensively employed by manyservice providers. READ MORE

  6. 4. Comparison of Cassini results with experiments at NASA Ames for the Enceladus plume, and calculations for a mission to Enceladus

    University essay from Luleå tekniska universitet/Tillämpad fysik, maskin- och materialteknik/Fysik

    Author : Ranj Amin; [2009]

    Abstract : Enceladus is the most astonishing and remarkable moon that has been found in the Saturn system. In 2005, when the spacecraft Cassini discovered Enceladus geologically active South Pole, more studies and research started to be conducted. READ MORE

  7. 5. Investigation of Enceladus plume composition, and the possibility of a sample return mission

    University essay from Luleå tekniska universitet/Tillämpad fysik, maskin- och materialteknik/Fysik

    Author : Martin Klasson; [2009]
    Keywords : Enceladus plume composition; spacecraft trajectories; enceladus; NASA; Fysik; astrobiologi; astrobiology; physics; NASA Ames; life in the solar system;

    Abstract : The discovery of Enceladus geologically active south pole by the Cassini spacecraft 2005 shifted focus to this small icy moon of Saturn. Methane and other hydrocarbons were detected in the plume emerging from Enceladus south pole, extending thousands of kilometers into space. READ MORE
