    Exergy analysis gas turbine cycle For EEs

    hi friends, I am working EES software for thermodynamic lesson,I am analyzing second law efficiency(exergy efficiency) and exergy analysis for all components of gas turbine cycle. Now I have a problem,exergy efficiency of turbine decrease with increasing before temperature,why? As you know...

    Guidance in Gambit 2.4 -- How change airfoil chords in Wells turbine model?

    hi my dear friends, Wells turbine is the subject of the my Thesis: http://www.upload7.ir/imgs/2014-10/37346220310608280524.jpg i make below model in gambit 2.4 ,But now I want to make the upper airfoil cord bigger than the bottom one. below model is constant,attention to third pictures(...
