Self-excited thermoacoustic instabilities as frequently observed in rocket motors, gas
turbines, ramjets, and aeroengine afterburners are highly detrimental and undesirable for …

The present experimental investigation is concerned with combustion dynamics of lean-
premixed multislit hydrogen-air flames, with the aim of addressing some of the central …

Abstract The Combustion Dynamics group in the Rocket Propulsion Department at the
German Aerospace Center (DLR), Lampoldshausen, strives to advance the understanding …

We present a data-driven method for the early detection of thermoacoustic instabilities.
Recurrence quantification analysis is used to calculate characteristic combustion features …

The article investigates liquid oxygen (LOx)–methane supercritical combustion dynamics in
a multi-element rocket-scale combustor using large eddy simulation (LES). A complex …

This work addresses the nature of supercritical hydrogen-oxygen flame coupling to
acoustics through visualization under conditions representative of upper-stage rocket …

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 …

A methane/oxygen mixture is considered to be an appropriate propellant for many future
rocket engines due to its practicality and low cost. To better understand the combustion …

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 …

To suppress the high frequency combustion instability of rocket engines, quasi-direct current
(quasi-DC) discharge plasma is considered in combination with special arrangements in a …
