Simulation of unsteady combustion in a LOX-GH2 fueled rocket engine

Stochastic modelling of transverse wave instability in a liquid-propellant rocket engine

“…At this time, large-eddy simulations exist for simple configurations. There are several single injector studies (Oefelein & Yang 1998;Oefelein 2006;Tucker et al 2007;Yang, Cuoco & Oschwald 2007;Tucker et al 2008;Masquelet et al 2009;Masquelet & Menon 2010;Schmitt et al 2010Schmitt et al , 2011Guézennec, Masquelet & Menon 2012), but systematic large-eddy simulation of a multi-injector system is still to be demonstrated.…”

Dynamics of a transcritical coaxial flame under a high-frequency transverse acoustic forcing: Influence of the modulation frequency on the flame response

“…Efforts to model and simulate real-gas effects [47][48][49][50][51][52][53][54][55][56][57] in an unsteady transcritical combustion have allowed to examine flame structures and dynamics by making use of large eddy simulations (LES). LES of transcritical coaxial jets and flames [58][59][60][61][62][63][64][65] show that it is possible to obtain reasonable predictions of transcritical flames and that such simulations could be used to explore transcritical jets and flames behavior under acoustic forcing as demonstrated in [66][67][68][69].…”

Large eddy simulations of multiple transcritical coaxial flames submitted to a high-frequency transverse acoustic modulation

“…In the past decade, efforts have been made to establish computational methodologies for transcritical injection and combustion including real gas thermodynamics, transport models and modified algorithms for numerical integration. LES of turbulent transcritical jets and jet flames have been carried out in the transcritical range by various research groups ( [11][12][13][14][15][16][17][18][19]) in the case of a coaxial flame formed by a transcritical oxygen stream surrounded by an annular flow of hydrogen or methane. Also, a couple of simulations of cryogenic H 2 O 2 jet flames and their interaction with transverse acoustic modes were performed [20,21] but results were not compared with experimental data in terms of the flame structure and dynamics.…”
