Cold flow modeling of the combustion chamber for a multi-fuel turbine engine

This article analyses the possibility of using a multi-fuel turbine engine as a primary source in hybrid systems. Turbine engines, thanks to their high efficiency and flexibility in using different types of fuels, can play a key role in integration with hybrid systems that combine electric drive with traditional energy sources. Additionally different fuels may influence combustion temperatures and soot formation, affecting thermal loads and material degradation. The proposed meth-odology will consist of conduct a comprehensive review of current models of combustion chambers in turbine engines, focusing on multi-fuel capability and hybrid applications. As a result, it will allow to identify key performance parameters (efficiency, emis-sions, stability, etc.) and define system requirements for hybrid optimization. The article presents comparative analysis of which geometry performs best for multi-fuel combustion. The model results were then compared with literature data. The conducted modelling of a multi-fuel combustion chamber intended for use in hybrid turbine systems has shown that the choice of fuel significantly influ-ences combustion behaviour, temperature distribution, and emission profiles. Nevertheless, the developed model provides a solid foundation for future integration into hybrid propulsion architectures, offering adaptability to various fuels and operating regimes.
