An atmospheric combustor model with optical access for non-premixed swirl-stabilized
flames was developed in order to investigate the combustion behavior of gas turbine fired with lowcaloric
syngases and to create a data-base for the validation of numerical combustion models.
In the present work, newly developed fully 3-D PIV measurements of the combustor aerodynamics at
cold conditions are presented together with detailed wall temperature measurements in hot conditions.
These data are respectively used to validate the combustor numerical model from an aerodynamic
point of view and as boundary conditions when combustion simulations with different approaches are
carried out. Thermocouple traverses data and global emissions analyzers results are then used as
reference data for combustion models validation. Propane, as reference fuel, and a synthetic mixture of
CH4, CO, CO2, H2 are considered.
