Coupled Fluid Dynamic and Heat Transfer Analysis of a Small-Sized Research Gas Turbine Combustion Chamber

Absztrakt

In phase of design and development of gas turbine jet engines, it is indispensable to be aware of the complex physical, chemical, fluid dynamic, heat transfer and thermodynamic phenomena occurring inside the main engine parts. With use of CFD tools and visualisation techniques, engineers are able to reveal and better understand the elaborate and hidden processes in gas turbine engines. The aim of this study is to perform a coupled fluid dynamic and heat transfer analysis on a small-sized research gas turbine combustion chamber with special care for the accuracy of combustion process and outlet temperature distribution compared to the combustion-theory requirements and to available and suitable data for verification. The plausibility check was accomplished with the results of a MSc thesis and an ongoing PhD dissertation with same geometry and similar conditions and objectives.
