A non-intrusive reduced-basis (RB) method is proposed for parametrized unsteady flows. A
set of reduced basis functions are extracted from a collection of high-fidelity solutions via a …

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 …

This work presents a model reduction approach for problems with coherent structures that
propagate over time, such as convection-dominated flows and wave-type phenomena …

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 …

This paper presents the first numerical evidence of an intermittency route to period-2
thermoacoustic instability in a subcritical singleelement liquid rocket engine burning …

Beating, a specific oscillation mode of combustion instability, occurred in a premixed
hydrogen fueled Rijke tube was investigated. A two-dimensional transient numerical model …

Self-excited longitudinal combustion instabilities were analyzed in a sub-scale combustor
operating with a propellant combination of O 2/CH 4. Couplings between acoustics …

This article experimentally investigates the suppressing of combustion instability in a model
gas turbine combustor with annular air jets. Three parameters were optimized to find the …

A 7-element rocket combustion chamber using GOX/GCH 4 as propellant has been modeled
and simulated to get a more comprehensive knowledge for combustion and heat transfer …

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 …
