Summary
Experimental results are reported which were measured as flow-field data for numerical modelling and with the aim to explore the flow dynamics in a model combustion chamber with and without the presence combustion. The flow was driven by a dual-flow swirl nozzle. With the help of laser-Doppler and flow visualisation techniques the isothermal and the combusting flow fields were mapped with all coefficients of the Reynolds-stress tensor. Frequency spectrum analysis was executed of the velocity-components’ fluctuations and of the acoustic emission. The results show a strong and stable anisotropy of the turbulence and an absolutely unstable behaviour that forms a highly coherent helical structure at least in the cold and non-reacting zone upstream of the elevated flame. Most of the discussed results compare the non-reacting with the reacting flow-fields where methane gas was applied as a fuel.
