Real-Gas-Flamelet-Model-Based Numerical Simulation and Combustion Instability Analysis of a GH2/LOX Rocket Combustor with Multiple Injectors

نویسندگان

چکیده

A large eddy simulation (LES) and combustion instability analysis are performed using OpenFOAM for the multiple shear-coaxial injector combustor DLR-BKD (in German Deutsches Zentrum für Luft–Brennkammer D, Aerospace Center–Combustion Chamber D), which is a laboratory-scale operating in real-gas environment. The Redlich–Kwong–Peng–Robinson equation of state steady-laminar flamelet model adopted to accurately capture effects. Moreover, stable under LP4 condition numerically analyzed, characteristics flow field investigated. In numerical instability, generated by artificially superimposing 1st transverse standing wave solution on solution. To decompose mode, dynamic mode decomposition method applied. Several modes qualitatively quantitatively identified through contour plots graphs, sustenance process limit cycle

A flamelet-based model for supersonic combustion

The renewed interest in high-speed flight has recently demonstrated the need for the development of hypersonic air-breathing propulsion systems, i.e., in which the ambient air is used as oxidizer. These systems have long been recognized as the most well-suited for hypersonic propulsion. Although a traditional ramjet is most appropriate for supersonic speeds (Mach 3 to 5), hypersonic speeds (Mac...

3-D Numerical Simulation of Gas Turbine Combustor

This paper presents a numerical solution for a changing combustor geometry. The effects of the geometric change on the main parameters of the chamber are considered. For this purpose the original geometry and the new one are simulated numerically by a 3-D CFD code and the results are compared. Finally, comments are presented regarding this change. A model is used for turbulence modeling and a...

Numerical Simulation of a Low Emissions Gas Turbine Combustor Using KIVA-II Part II: Quick-Quench/Lean-Combustion Zones Analysis

SUMMARY This is the second part of the numerical investigation on a low emissions staged turbine combustor (STC) using a modified version of the KIVA-II code. The main focus of this study is the numerical analysis of the reacting fluid flow and heat transfer inside the quick-quench/lean-combustion (QQ/LC) zones. In the QQ zone, cool dilution air was injected into the hot mixture through eight 4...
