Proc. ASME. GT2022, Volume 3A: Combustion, Fuels, and Emissions, V03AT04A036, June 13–17, 2022
Paper No: GT2022-81339
... of the certification process, numerical simulations can be used to assess the impact of a new fuel on combustion. Further, the detailed simulations provide an insight into the fuel sensitive sub-processes. The lean blowout (LBO), i.e. the lower stability limit of a gas turbine combustor, is of primary concern for safe...

Proc. ASME. GT2021, Volume 3A: Combustion, Fuels, and Emissions, V03AT04A020, June 7–11, 2021
Paper No: GT2021-58830
..., i.e. lean blowout of turbulent hydrogen/ammonia/air flames, is experimentally investigated in a generic non-swirl premixed burner at atmospheric conditions. Special focus is laid on a measurement setup with fully automatized measurement procedure, to reach the stability limits, as these limits tend...
