Article
Being able to ignite or reignite a gas turbine engine in a cold and rarefied atmosphere is a critical issue for many manufacturers. From a fundamental point of view, the ignition of the first burner and the flame propagation from one burner to another are phenomena that are usually not studied. The present work is a large eddy simulation (LES) of t...

Accurate characterization of swirled flames is a key point in the development of more efficient and safer aeronautical engines. The task is even more challenging for spray injection systems. On the one side, spray interacts with both turbulence and flame, eventually affecting the flame dynamics. On the other side, the structure of turbulent spray f...

In this paper we present and implement the Palindromic Discontinuous Galerkin (PDG) method in dimensions higher than one. The method has already been exposed and tested in [4] in the one-dimensional context. The PDG method is a general implicit high order method for approximating systems of conservation laws. It relies on a kinetic interpretation o...

Full-text available
Large Eddy Simulation (LES) and Direct numerical Simulation (DNS) of polydisperse evaporating sprays with Eulerian models are very promising tools for high performance computing of combustion applications since they are able to predict the turbulent dispersion and evaporation. However, the spray system of conservation equations has a convective par...

Ignition is a critical process in combustion systems. In aeronautical combustors, altitude relight capacities are required in case of accidental extinction of the chamber. A simultaneous study of light-round ignition in an annular multi-injector combustor has been performed on the experimental and numerical sides. This effort allows a unique compar...
Article
This paper presents a large eddy simulation (LES) of flow and heat transfer in a tandem configuration of two square cylinders at moderate Reynolds number (Re = 16; 000). Compressible LES on a hybrid mesh is used to predict the flow structure and the heat transfer at the wall. The goals of this work are to analyze the flow and the heat transfer arou...
Article
The ignition transient is a critical fundamental phase in combustion systems that has strong practical implications. While this phenomenon has been extensively studied on single injector configurations, the burner-to-burner propagation of a full annular combustor is rarely investigated, due to the size and complexity of the geometry involved. To th...
Conference Paper
Full-text available
The study focuses on the full simulation of a multiple coaxial configuration which typifies, on a model scale, the geometry and the thermodynamic and injection conditions found in real rocket engines. Cryogenic reactants (liquid oxygen and gaseous methane) are injected under transcritical conditions, a situation reached when the pressure is higher...
Article
Full-text available
Ignition is a problem of fundamental interest with critical practical implications. While there are many studies of ignition of single injector configurations, the transient ignition of a full annular combustor has not been extensively investigated, mainly because of the added geometrical complexity. The present investigation combines simulations a...
Article
Abstract This article describes a numerical investigation that explores the dynamics of multiple cryogenic jet flames interacting with high frequency transverse acoustic modes. This research is motivated by the numerous issues associated with high-frequency instabilities in liquid rocket engines. Large eddy simulations are carried out in a complex...
Article
Full-text available
Combustion is essential to modern air and space propulsion. While steady operation of engines under nominal conditions is reasonably well understood and simulated, less is known about the dynamics of combustion and the possible instability problems which may arise in these high performance devices. To optimize engine performance and limit instabili...
Article

This paper presents a method of large-eddy simulation on unstructured grids designed to predict the wall heat transfer in typical aeronautical applications featuring turbulent flows and complex geometries. Two types of wall treatments are considered: a wall-function model using a full tetrahedral grid and a wall-resolved method computed on a hybrid...

Large eddy simulation (LES) gives access to unsteady flame behaviours as encountered during transient ignition.
Conference Paper
Large eddy simulations (LES) of a turbulent jet premixed flame are performed using a dynamic formulation for the flame surface wrinkling factor entering the F-TACLES combustion model. The model parameter is automatically adjusted on the fly, taking advantage of the knowledge of the resolved scales in the flow field. Three cases are considered: a gl...
Article
The relevant description of a flame kernel growth in homogeneous isotropic turbulence environment is a key ingredient for the simulation of combustion in spark-ignited internal combustion engine. A small flame kernel burns at an increasing rate as it grows and becomes progressively more and more wrinkled by the prevailing turbulence. Large eddy sim...
Article
Large-Eddy Simulation of transcritical combustion is considered in this article. This analysis is motivated by rocket propulsion applications where cryogenic oxygen is injected at low temperature, below the critical value, in a high pressure environment where the pressure is above critical. Problems encountered in this range are related to the desc...
Article
A dynamic version of the thickened flame model for large eddy simulations (TFLES) of turbulent premixed combustion is implemented by coupling two independent codes through MPI (Message Passing Interface) running on massively parallel machines. The combustion code, AVBP, solves the usual filtered Navier–Stokes, mass fractions and energy balance equa...

Large Eddy Simulation (LES) and Direct numerical Simulation (DNS) of polydisperse evaporating sprays with Eulerian models are very promising tools for high performance computing of combustion applications. They are able to describe the turbulent dispersion and evaporation and properly predict the combustion regimes. However, the spray system of con...

In practical flow congurations, a large disparities of geometrical length scales are often encountered. Inside a combustor, for example, the ratio between the diameter of the injection holes and the size of the entire combustion chamber may present several orders of magnitude. When considering an explicit solver for fully compressible Navier-Stokes...

In the context of numerical simulation of combustion, large disparities of geometrical length scales are encountered in combus- tion chambers. Indeed, differences in mesh cell sizes between a small injector and the overall combustion chamber may present several orders of magnitude. When considering an explicit solver for fully compressible Navier-S...

An extension of the large eddy simulation (LES) technique to two-phase reacting flows, required to capture and predict the behavior of industrial burners, is presented. While most efforts reported in the literature to construct LES solvers for two-phase flow focus on Euler–Lagrange formulation, the present work explores a different solution (‘two-f...

L'allumage ou le rallumage d'une turbine à gaz dans une atmosphère froide et raréfiée est un problème crucial pour les constructeurs aéronautiques. Le but de cette thèse est de développer une méthode de simulation aux grandes échelles (LES) pour étudier la combustion et l’allumage dans les géométries réalistes de foyers aéronautiques. L’approche th...

Large Eddy Simulation (LES) is now recognized as an efficient numerical tool to predict gaseous combustion in industrial burners, and a number of examples of applications can be found in the literature. In these examples, the accuracy and the pre-dictive capacity of LES are clearly demonstrated, even for unsteady phenomena. However most industrial...

Ground ignition and altitude re-ignition are critical issues for aeronautical gas turbine design. They are strongly influ- enced by the turbulent flow structure as well as the liquid fuel spray and its atomization. Turbulent mixing, evaporation and combustion that control the combustion process are complex unsteady phenomena coupling fluid mechanic...

Being able to ignite or reignite a gas turbine engine in a cold and rarified atmosphere is a critical issue for many manu-facturers. In the Vesta combustor of Turbomeca, 18 main burners are ignited by two pilot flames. The success of an ignition attempt depends on the completion of three steps. In a first step, a spark plug must ignite the fuel spr...
