  1. 21. Network Modeling Application to Laminar Flame Speed and NOx Prediction in Industrial Gas Turbines

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära; Linköpings universitet/Tekniska högskolan

    Author : Seyedeh Sepideh Marashi; [2013]
    Keywords : Gas turbine; combustion; NOx; emissions; laminar flame speed; burning velocity; hydrogen; network modeling; reactor network modeling;

    Abstract : The arising environmental concerns make emission reduction from combustion devices one of the greatest challenges of the century. Modern dry low-NOx emission combustion systems often operate under lean premixed turbulent conditions. READ MORE

  2. 22. Simplification of 3d cooled turbine blade models for efficient dynamic analyses

    University essay from KTH/Kraft- och värmeteknologi

    Author : Arokia Arokia Lourdu Marshall; [2013]
    Keywords : SGT-750; Cooled turbine blades;

    Abstract : In gas turbines, the temperature behind the combustors is the highest, meaning that the blades in the first stage of the turbine require cooling air. This makes the structural blade model very detailed due to the presence of the cooling pattern. READ MORE

  3. 23. Flexible Ignition System for a Gas Turbine

    University essay from KTH/Kraft- och värmeteknologi

    Author : Anton Berg; [2012]
    Keywords : Gas turbine; ignition; methane; propane; CO2; N2; ignition energy; ignition delay time;

    Abstract : Siemens Industrial Turbomachinery AB produce five gas turbines models. The SGT-700 can currently only start on gases which contain low amounts of inert gases. It is therefore of interest to widen the fuel range which the SGT-700, as well as other gas turbines, can start on. READ MORE

  4. 24. Numerical Study of NOx and Flame Shape of a DLE Burner

    University essay from Mekanisk värmeteori och strömningslära; Tekniska högskolan

    Author : Naser Hamedi; [2012]
    Keywords : CFD; combustion; NOx emission; flame shape; burner;

    Abstract : For natural gas combustion, there is a large amount of experience in the gas turbine industry. However, much of the design work is based on costly combustion tests due to insufficient accuracy of existing prediction tools for data such as emissions and effects due to fuel composition. READ MORE

  5. 25. Application of CFD to Safety and Thermal-Hydraulic Analysis of Lead-Cooled Systems

    University essay from KTH/Fysik

    Author : Marti Jeltsov; [2011]
    Keywords : Coupled Codes; Verification Validation; CFD; System Thermal-Hydraulics; Lead Cooled sys-;

    Abstract : Computational Fluid Dynamics (CFD) is increasingly being used in nuclear reactor safety analysis as a tool that enables safety related physical phenomena occurring in the reactor coolant system to be described in more detail and accuracy. Validation is a necessary step in improving predictive capability of a computationa code or coupled computational codes. READ MORE
