I am working on simulations of Gas turbine, and i want to see how the thermal efficiency of gas turbine varies by reducing the load on Gas turbine and heat exchangers (e.g. Compressor Inter cooler) etc.
hi Haris, the gas turbine are very sensitive to off-design condition. if you are modelling a gas turbine for electrical generation at constant rpm is the worst condition because the compressor efficiency is really affecetd at low loads. that the reason of the inlet guide vane at the inlet and the several blade wheel with variable geometry, because constant rpm in absence of that devices always produce the same air flow disregarding the load value. There are papers where you can find a comprehensive study about that . Look in internet the papers written by Rainier kurtz ( engineer in carter pillar)
