Rocket engines are prone to suffer from transverse combustion instabilities, manifesting as
periodic oscillations in pressure and heat release rate. Self-excited transverse instabilities in …

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

To understand the fundamental properties of newly attractive oxygen (O 2)/methane (CH 4)
bipropellants, the combustion characteristics of O 2/CH 4 coaxial jet flames in a model …

The bifurcation process of self-sustained combustion instability pressure perturbations in a
liquid rocket combustor is investigated based on the Helmholtz equations and a pressure …

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 …

The objective of this research is to study the impact of main engine parameters on the
performance of a reusable liquid propellant rocket engine (LPRE). For this purpose, after a …
