Combustion dynamics constitutes one of the most challenging areas in combustion
research. Many facets of this subject have been investigated over the past few decades for …

In a thermoacoustic system, such as a flame in a combustor, heat release oscillations couple
with acoustic pressure oscillations. If the heat release is sufficiently in phase with the …

High order accurate weighted essentially nonoscillatory (WENO) schemes are relatively new
but have gained rapid popularity in numerical solutions of hyperbolic partial differential …

Essentially non-oscillatory (ENO) and weighted ENO (WENO) schemes were designed for
solving hyperbolic and convection–diffusion equations with possibly discontinuous solutions …

Nonlinear features of flame dynamics are characterized by measuring the flame transfer
functions for different input levels. This provides a family of gain and phase curves, which …

Thermoacoustic instability, also known as combustion instability, continues to be a problem
in the development of modern gas turbine combustors and rocket engines. Such instability is …

The present paper describes a methodology to improve the accuracy of prediction of the
eigenfrequencies and growth rates of self-induced instabilities and demonstrates its …

Self-excited oscillations in low emission, premixed combustion systems are often caused by
feedback between unsteady heat release rates and reactive mixture equivalence ratio …

An inverted conical flame anchored on a central bluff-body in an unconfined burner
configuration features a distinctive acoustic response. This configuration typifies more …

The ignition transient is investigated in this article in a laboratory-scale multiple injector
configuration. The analysis specifically focuses on the “light-around” mechanisms that …
