Boundary layer flashback prediction for high hydrogen flames at gas turbine burner geometry and operating conditions

The idea of using hydrogen as a medium for storing excess renewable energy is gathering momentum but to deliver, several technological advances are required. One of the main challenges is boundary layer flame flashback (BLF) as a key operability issue for low NO_x premixed combustion of hydrogen-enriched fuels; thus design of tools to...

Boundary layer flashback prediction of a low emissions full hydrogen burner for gas turbine applications

A highly accurate model is presented that predicts boundary layer flashback (BLF) for lean premixed hydrogen combustion. In contrast to existing models, that fail for lean hydrogen mixtures, the present model includes the effect of flame instabilities. The model is applied to study the effect of burner geometry on flashback tendency. A diverging...
