Experimental data of the TU Delft partially premixed swirl stabilized CH4/H2 burner

Experimental dataset of the TUD partially premixed swirl stabilized burner for fuel-flexible combustion (CH4/H2). Acquired in the Sustainable Aircraft Propulsion Laboratory of the Delft University of Technology between 2022 and 2025.

The dataset consists of the following measurement data:

Non-reacting average flow fields in the mixing tube and the combustion chamber with surrogate fuels representing the CH4/H2 mixtures
Results of SPOD on non-reacting flow fields (spatial and temporal modes)
Reacting average flow fields in the combustion chamber for different CH4/H2 mixtures
OH-PLIF data (qualitative)
NO and CO2 emission data taken in the exhaust gases


The methodology, file description, naming convention, and set-up description are included in the README.pdf file.
