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.<br>The dataset consists of the following measurement data:<br>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 <br>The methodology, file description, naming convention, and set-up description are included in the README.pdf file.<br>
