| description | Research and development in understanding the responses of acoustic excitation as a
meant to influence flame behavior have become one of the significant issues in
combustion instability. This interaction can be found in most processing, power
generating, and propulsion application. Some of the responses that can be seen from
the interaction are lift-off phenomenon, changes of flame macroscopic structure, and
production of emission that contribute to the environment. However, it seems there
are insufficient data that were focusing mainly on the change of flame properties and
how it's being affected by the increase of acoustic excitation. The need to publish
some of the significant results and helps improve the understanding of combustion
instabilities became the major motivational in conducting the research. This study
adopted experimental research and understanding the change of flame behavior by
differentiates two number of speakers (source of acoustic) excited to the flame. For
data collection, it employs a direct imaging technique using a DSLR camera. The
data obtained were analyzed using image processing software, Image J. This
experiment focuses on the change of flame properties based on the number of the
speaker (source of acoustic) used with the increased number of frequencies. The
flame shape obtain in this experiment is divided into disturbances and un-disturbance
categories, and each shape is then thoroughly discussed by focusing on the change of
its length, width, and angle. The results from this experiment shows that the response
of flame is significantly affected by the configuration of speakers (sound source) and
the magnitude of amplitude used. It indicated that for dual speakers and higher
amplitude in terms of its flame characteristic shows a promising flame response
compare with a single speaker and lower amplitude |
