  • This week, the IFRF Handbook adds to its combustion noise portfolio with the publication of three Combustion Files describing the causes and cures for combustion driven oscillations, also sometimes referred to as ‘resonance’ or ‘instability’.

    295 What is the Rayleigh Criterion for Combustion Driven Oscillations? – Open Domain
    296 How do I apply the Rayleigh Criterion to suppress organ pipe Combustion Oscillations? – Members’ Domain
    297 How do I apply the Rayleigh Criterion to suppress Helmlholtz cavity Combustion Oscillations? – Members’ Domain

    Combustion driven oscillations are, fortunately, a relatively rare phenomenon. When they do occur, however, they can lead to intractable noise problems or even to mechanical damage, i.e. they cannot simply be ignored. Jim Seebold of the American Flame Research Committee has prepared three combustion files to share with us his knowledge and experience of dealing with this phenomenon both from a basic and from a practical standpoint.

    IFRF Members may read or download these Combustion Files at www.handbook.ifrf.net, by selecting ‘New Combustion Files’ after accepting the disclaimer screen. Other Combustion Files on related themes may be found by searching the Handbook with the  keyword ‘noise’. Non-members may also access CF295 and other open domain Combustion files. Jim’s work has been submitted in its entirety for future publication to the IFRF Journal, where it will be in the public domain in due course.
