15. Conclusions
The hex has considerable effect in the thermoacoustic response of the system, when close to the flames
The transition from envelope impingement regime to cool central core significantly changes the system behavior
The burner-hex distance is very critical and can lead to measurement uncertainties

16. Acoustic measurements of real scale heat exchangers
Far Future Work
Measurements of the fluctuations of the heat flux through the heat exchanger (sensitive heat flux sensors)
More detailed CFD modelling (DNS) of intrinsic flame instabilities in real scale burners
Acoustic measurements of real scale heat exchangers
