“…In that same study, Agbadede et al [52] compared the effect of the use of hydrogen and natural gas on the HPT blade's creep life (creep is one of the most common failure mechanisms that reduce component life). The result also shows an improved creep life when hydrogen was used rather than natural gas, which is in line with other literature reviews [53] on the longer engine life and lower maintenance costs for LH2.…”

In the present work is made an overview of the use of hydrogen in aviation, the modifications needed to convert a conventional gas turbine to use hydrogen and a CFD simulation of an existent gas turbine burning hydrogen. The CFD simulation was done in a CFM56-3 combustor burning Jet A (as a reference standard) and hydrogen, with the intention of evaluate the viability of conversion of existent gas turbines to hydrogen, in a combustion point of view, by analyzing the emissions through ICAO’s LTO cycle while burning this fuel. ANSYS Fluent 2020R2 was the software used to perform the numerical study. The RSM was the viscous model used. Only the NOx emissions were assessed as pollutant once the hydrogen combustion products are reduced to water vapor and NOx. These emissions were evaluated through a detailed mechanism and the NOx model available on ANSYS to get a better concordance with the ICAO’s values. During this study, several sensibility studies were carried out for hydrogen burn, for instance, the analysis of the air flow with/without swirl in the primary zone and different inlet pressure and temperature for fuel.

“…Aside from the LH2 and jet fuel comparison on creep life, Agbadede et al [35] compared the hydrogen fuel and natural gas effect on the HPT blade's creep life for an industrial gas turbine. The result also shows an improved creep life when hydrogen fuel was used rather than natural gas, which aligns with other literature reviews [2] on the longer engine life and lower maintenance cost for LH 2 . It is expected for a new engine program that the engine's first overhaul is after approximately 10,000 h [56].…”

“…In recent years, liquefied hydrogen (LH 2 ) as a fuel for gas turbines has received fresh traction both in aero and industrial applications, due to its potential benefit of allowing very clean combustion and zero-carbon emission [1]. With the growing demand for stringent environmental regulations on fossil fuel, it is predicted that hydrogen could be a viable alternative for jet fuel [2,3]. It has an extensive stability limit, global availability, reduced noise, and low maintenance cost.…”

Thermodynamic Performance and Creep Life Assessment Comparing Hydrogen- and Jet-Fueled Turbofan Aero Engine

et al. 2021

There is renewed interest in hydrogen as an alternative fuel for aero engines, due to their perceived environmental and performance benefits compared to jet fuel. This paper presents a cycle, thermal performance, energy and creep life assessment of hydrogen compared with jet fuel, using a turbofan aero engine. The turbofan cycle performance was simulated using a code developed by the authors that allows hydrogen and jet fuel to be selected as fuel input. The exergy assessment uses both conservations of energy and mass and the second law of thermodynamics to understand the impact of the fuels on the exergy destruction, exergy efficiency, waste factor ratio, environmental effect factor and sustainability index for a turbofan aero engine. Finally, the study looks at a top-level creep life assessment on the high-pressure turbine hot section influenced by the fuel heating values. This study shows performance (64% reduced fuel flow rate, better SFC) and more extended blade life (15% increase) benefits using liquefied hydrogen fuel, which corresponds with other literary work on the benefits of LH2 over jet fuel. This paper also highlights some drawbacks of hydrogen fuel based on previous research work, and gives recommendations for future work, aimed at maturing the hydrogen fuel concept in aviation.
