ABSTRACT

Comparative analysis of the combustion of methane air mixture in gas turbine Can- combustion chamber is presented in this study. The analysis is done on CFD software with CFX solver. The motive of this study is to understand the combustion phenomena and resulted emissions. With the high cycle temperature of modern gas turbine, mechanical design remains difficult and a mechanical development program is inevitable. The rapidly increasing use of Computational Fluid Dynamics (CFD) in recent years has had a major impact on the design process, greatly increasing the understanding of the complex flow and so reducing the amount of trial and error required. The gas turbine Cancombustion chamber is designed to burn the fuel efficiently, reduce the emissions, and lower the wall temperature. In this study the mathematical models used for combustion consist of the PDF Flame let Model and Eddy Dissipation Combustion Model for non premixed gas combustion. The outcome of the work will help in finding out the predictions of PDF Flame let Model and Eddy Dissipation Combustion Model for non premixed gas combustion with geometry of the combustion chamber which will lead to less emission.
