Abstract:

 

Detection and imaging of multi-reaction zones is an  essential tool for understanding the detailed structure of complicated  flames.  In this work a combined 4-camera technique is presented for  multi-reaction zones imaging.  The technique combines highly advanced  laser-based diagnostics tools, namely Rayleigh scattering,  laser-induced predissociation fluorescence (LIPF) of OH, LIF of PAH,  and LIF of formaldehyde (CH2O).  The application of this combined  technique in turbulent non-homogeneous hydrocarbon flames is quite  new.  The technique shows its ability to detect simultaneously rich,  lean and diffusion reaction zones.  The 3 reaction zones can be  spatially resolved, providing essential information about their  interaction and overall flame stability.  Therefore, the detection and  study of triple flame structures in non-homogeneous turbulent flames  becomes possible.  An example of a triple flame structure in a  turbulent lifted non-premixed methane flame is presented.  The present  work proves that the developed technique is a powerful tool for  multi-reaction zone measurements in turbulent and laminar flames.
