Analytic Approximation of Non-Periodic Dynamical System by Perturbation Method

Abstract

In this paper, a steady-state flow modelling and simulation of an SGT5 -2000E gas turbine model was carried using Ebsilon Professional Software. The design and off-design conditions were considered according to the environmental ambient air temperature. The model results were validated using design and actual operating data by applying the error percentage analysis. The validated results obtained ranged from -3.13% to 0.88% for design condition, while -3.24% to 2.66% for off-design condition. In addition, the model validation results were found to be in good agreement with the actual installed operating data. Thus, the model data obtained can be utilized for further studies such as energy, exergy and environmental analyses.
