Model development for gas turbine performance assessment using ANSYS fluent software

This study develops a computational fluid dynamics (CFD) model for performance assessment of a gas turbine. In doing this, a comparative analysis of an ideal performance of the gas turbine modelled in 2D has been made to the actual performance of the system. The study developed methods and suggestions for increasing the accuracy of the data captured by ET 792 gas turbine as well as increasing the efficiency of some of the components of gas turbine. This has been done through the use of individually modelled components of the gas turbine allowing for a more in-depth understanding of the mixing of the air and fuel, and the corresponding pressures and flows present in the system. Furthermore, different designs of combustions chamber and inlet were created to analyse the effectiveness of the new designs. Finally, the inlet for the gas turbine was altered to help increase the accuracy of the mass flow reading of the air flowing through the systems and a suggestion was made for increasing the effective air fuel mixing in the combustion chamber resulting in evenly distributed force on the turbine blades.
