In this study, the effects of various system parameters on combustion instability were numerically identified through a network-based thermoacoustic model using the concept of a transfer function. The acoustic transfer function was derived from the w

Blowoff limits are essential in establishing the combustor operating envelope. Hence, there is a great demand for practical aero-engines to extend the blowoff limits further. In this work, the behavior of non-premixed swirling flames under fuel flow
