Sensitivity Analysis on Brayton Cycle Gas Turbine Performance

This paper evaluates the performance of a Brayton cycle gas turbine, in terms of Introduction The behavior of gas turbine power plants, like that of every energy system, is usually described by suitable models that, depending on their precision and complexity, reproduce working conditions more or less accurately. These models are often employed to determine or verify the performance of an energy system, using numerical values of different input variables, which affect calculation results to a varying extent, according to their chosen value If, as seems evident, each input variable has a different weight on the numerical results, the establishment of a sensitivity parameter defining this weight can be of considerable interest. In addition, this parameter permits one to compare the relative incidence of each of the above-mentioned input variables and, therefore, to establish which of them require a more precise choice of the value to be attributed
