Description
Summary:The paper presents the thermodynamic analysis for changing the fuel of an aviation gas turbine from kerosene to alternative gaseous fuels. Theoretical results are obtained using the CEA program and the numerical ones using a commercial CFD code. The gas turbine used for the application is a helicopter turboshaft for which the geometry of the combustor was carefully reproduced in a CAD environment. The paper details each necessary step to obtain the numerical results, as well as some comparison with experimental data. The conclusions are related to the similarities and the differences between the presented numerical results, considering the complexity of the entire gas turbine. A series of development perspectives are presented.
