Since the early days of gas turbine engines,
combustion/flow instability inside the combustor has
been an issue in many engines, but little has been
understood as to how the dynamics of the system
involved contribute to the instability. The primary
objective of this work is to provide general
experimental procedures and to validate methods for
examining the dynamic behaviors of combustion
systems, and to provide accurate measurements of the
combustion dynamics for use as a foundation for
further theoretical and numerical research.
Knowledge of the fundamental dynamics of combustion
systems is crucial in understanding and modeling the
flame behavior and enabling the use of insights in
design process and for creating robust active control
of combustors.
The measurement technique used for the current work
is a laser-based, non-intrusive one that the flow
fields are not affected by probing for
measurements.
In addition to the measurement techniques, also
presented in this book are techniques to impose
acoustic effects on the flow fields along with
parameters to quantify the degree of mixing and
thermo-acoustic instability.
