In this work, we develop a 2D numerical model of a Y-shaped bifurcating combustor with a
Helmholtz resonator attached. Propane (C 3 H 8) is fueled and burnt with air by applying …

In this paper, we present the numerical evidence of multiple bifurcations in thermoacoustic
instability as we decrease the equivalence ratio (ϕ) from fuel-rich (ϕ= 1.5) to fuel-lean (ϕ …

The phenomena of combustion instabilities beyond limit cycles caused by the nonlinear
interaction of various instability modes have recently received much attention. This paper …

This paper provides the first numerical proof of intermittency routes existing before and after
thermoacoustic instability, as we increase the oxidizer inlet temperature under fuel-lean (ϕ …

Computationally efficient modeling of gas turbine combustion is challenging due to the
chaotic multi-scale physics and the complex non-linear interactions between acoustic …

This paper presents the first numerical evidence of the intermittency routes that exist before
and after the occurrence of thermoacoustic instability in a subcritical single-element liquid …

In this study, we present the first numerical evidence of multiple bifurcation processes
occurring in a multi-element model liquid rocket engine before and after the longitudinal …

Accurate, efficient prediction of reacting flow systems is challenging due to stiff reaction
kinetics, significant disparity in spatiotemporal scales, and multi-physics interactions …

In this study, the acoustic modes in a methane-fueled rocket engine combustion chamber
are modelled with different approaches of increasing complexity. A sub-scale thrust chamber …

Combustion instabilities have always represented a challenge for liquid rocket propellant
engines (LPREs). In LPREs, a great amount of energy is released during combustion and …
