Pulsed instabilities in combustion chambers [PDF]

open access: yes31st Joint Propulsion Conference and Exhibit, 1995
A pulsed or "triggered" instability occurs when pressure oscillations develop in a linearly stable combustion system after being subjected to a sufficiently large disturbance. Such true nonlinear instabilities usually occur as subcritical bifurcations in dynamical systems theory.

Low-frequency oscillations of combustion products in the chamber of a low-thrust liquid rocket engine manufactured using additive technologies

open access: yesАвіаційно-космічна техніка та технологія
Oscillations in engine thrust are due to nonstationary dynamic processes in the combustion chamber. The presence of vortexes in the combustion product flow in the combustion chamber can lead to liquid rocket engine (LRE) dynamic instability with a ...

LES of the Sandia Flame D Using an FPV Combustion Model [PDF]

open access: yesEnergy Procedia, 82 (2015), Pag: 402-409, 2016
The simulation of turbulent combustion phenomena is still an open problem in modern fluid dynamics. Considering the economical importance of hydrocarbon combustion in energy production processes, it is evident the need of an accurate tool with a relatively low computational cost for the prediction of this kind of reacting flows.
