CFD Analysis of an Aircraft Turbofan Engine Combustion Process and the Effect on Turbine
Öz
In this paper, a two-dimensional computational fluid dynamics (CFD) study of Turbofan engine is presented using the ANSYS Fluent program, the navier–stokes equations is used for analysis, including a two-dimensional and symmetrical drawing of both the combustion chamber and in a 1.5 Stage Axial Flow Turbine. A GE-90 turbofan engine nacelle was used with Naca 63-412 type blades were used for the analysis of the flow on the turbine blades. Combustion chamber simulations were carried out using a previous study.
The computational results were compared with other studies on the Exergetic analysis of a GE-21 turbojet engine. The GE-21 engine had a combustion chamber temperature of 2900 K, while the GE-90 engine had a temperature of around 2706 K. The previous study considered the velocity of fluid flow to be 200 m/s, whereas the velocity of flow in this study was 209 m/s as determined in the part of analysis and result.
