In a combustion chamber of a liquid rocket engine, acoustic fine-tuning of gas–liquid
scheme injectors is studied numerically for acoustic stability by adopting a linear acoustic …

A LIQUID rocket engine (LRE) requires a propellant supply system. Propellants can be
supplied by a turbopump or a propellant tank pressurized with inert gas. A turbopump …

THERE are two conflicting concerns in the development of new rocket engine combustors,
which include performance and stability. Generally, combustors of high performance have …

Acoustic design parameters of a half-wave resonator are studied experimentally for purely
acoustic tuning of the resonator. According to the standard acoustic-test procedures …

Acoustic dam** enhanced by gap width in baffled injectors is investigated numerically,
which are installed to suppress pressure oscillations in a model acoustic chamber. The …

This paper presents two case studies to evaluate passive stabilization in combustion
chambers by quantifying dam** capacity characteristics of acoustic cavities in combustion …

Acoustic dam** induced by a gas-liquid scheme injector is investigated numerically for
acoustic stability by adopting an acoustic analysis. The injector consists of four parts of a …

In a liquid rocket engine, the role of gas-liquid scheme injector as an acoustic resonator or
absorber is studied experimentally for combustion stability by adopting linear acoustic test …

Stability rating tests using a pulse gun, one type of artificial disturbance device, have been
performed to optimize and to limit the axial baffle length of a combustor. To determine …
