1. 21. Investigation on methods to improve heat loadprediction of the SGT-600 gas turbine

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Arman Farhanieh; [2016]
   Keywords : Gas Turbine; CFD; Turbomachinery; High Pressure Turbine; Heat Load; Time Transformation; Profile Transformation; Mixing Plane;

   Abstract : In modern gas turbines, with the increase of inlet gas temperature to raise thework output, the importance of accurate aero-thermal analysis has become of vitalimportance. These analysis are required for temperature prediction throughoutthe turbine and to predict the thermal stresses and to estimate the cooling requiredfor each component. READ MORE

3. 22. Simulation of Gas Channel Temperatures during Transients for SGT-800

   University essay from Lunds universitet/Institutionen för energivetenskaper

   Author : Tobias Johansson; [2016]
   Keywords : Technology and Engineering;

   Abstract : Siemens Industrial Turbomachinery has developed dynamic gas turbine models to compute performance parameters such as temperature, pressure, mass flow and power during transients. Results from the current dynamic model correspond to measured data except for gas channel temperatures that change too fast during transients. READ MORE

4. 23. Analysis and simulation of shading effects on photovoltaic cells

   University essay from Högskolan i Gävle/Avdelningen för bygg- energi- och miljöteknik

   Author : Sara Gallardo Saavedra; [2016]
   Keywords : shading; PV model; LT-Spice; photovoltaic energy; bypass diode; DC-DC optimizer.;

   Abstract : The usage of conventional energy applications generates disproportionate emissions of greenhouse gases and the consumption of part of the energy resources available in the world. It has become an important problem which has serious effects on the climatic change. Therefore, it is crucial to reduce these emissions as much as possible. READ MORE

5. 24. Thermo-mechanical fatigue crack propagation in a single-crystal turbine blade

   University essay from Linköpings universitet/Mekanik och hållfasthetslära

   Author : Andreas Koernig; Nicke Andersson; [2016]
   Keywords : Thermo-mechanical fatigue; crack propagation; single-crystal; turbine blade; FRANC3D;

   Abstract : Simulation of crack growth in the internal cooling system of a blade in a Siemens gas turbine has been studied by inserting and propagating cracks at appropriate locations. The softwares used are ABAQUS and FRANC3D, where the latter supports finite element meshing of a crack and calculation of the stress intensities along the crack front based on the results from an external finite element program.

6. 25. Sensor Validation Using Linear Parametric Models, Artificial Neural Networks and CUSUM

   University essay from Linköpings universitet/Reglerteknik; Linköpings universitet/Tekniska fakulteten

   Author : Gustaf Norman; [2015]
   Keywords : Sensor Validation; Linear Parametric Models; Artificial Neural Networks; ANN; Fault Detection; CUSUM;

   Abstract : Siemens gas turbines are monitored and controlled by a large number of sensors and actuators. Process information is stored in a database and used for offline calculations and analyses. Before storing the sensor readings, a compression algorithm checks the signal and skips the values that explain no significant change. READ MORE
