💡A Success Story about hydrogen as a potential green fuel💡
📋 "Investigation of hydrogen-enriched gas-turbine burner by Partially-Stirred Reactor Large Eddy Simulations (PaSR-LES)" by Fredherico Rodrigues da Silva, Jose Manuel Pastor, Daniel Mira and José M. Garcia-Oliver from Barcelona Supercomputing Center and Universitat Politècnica de València (UPV)
Gas turbine engines are key players in global trade and electricity generation, but they are run with regular, carbon-based fuels. Hydrogen is a promising alternative which, if stemming from renewable energy, should result in zero CO2 emissions. However, its dramatically different combustion properties make a redesign of the gas turbine burner completely necessary.
Achieving that requires accurate, advanced combustion models that enable an accurate prediction of the flame performance with hydrogen. This project assesses the prediction capabilities of a Perfectly-Stirred Reactor model for gas turbine-type burners. This kind of model assumes complete mixing within the reactor and is simpler to implement, at the cost of higher computational cost.
Thanks to RES supercomputer MareNostrum5 from Barcelona Supercomputing Center, the team investigated test cases based upon the PRECCINSTA burner fed with methane and increasingly larger amounts of hydrogen, with the outlook on a 100% hydrogen application.
The results show the model reproduces an interesting transition of the resulting flame from a "M" to a "V" shape when increasing the amount of hydrogen and will contribute to the improved leveraging of hydrogen flames.
