Large Eddy Simulation of laser ignition and compressible reacting flow in a rocket-like configuration
The control of ignition in a rocket engine is a critical problem for combustion chamber design. Delayed ignition may lead to high amplitude pressure fluctuations that can damage the burner (strong ignition) whereas early ignition may fail. This paper describes a numerical study of a strong ignition sequence observed in a laboratoryscale single-injector rocket chamber ignited by a laser and fuel...

15 صفحه اولLarge Eddy Simulation of a Turbulent Reacting Compressible Jet
We report results of a Large Eddy Simulation (LES) effort of turbulent compressible nonpremixed reactive jets. It is well known that there are several difficulties associated with compressible reactive flows in comparison with incompressible flows. In incompressible flows, the energy and mass conservation (for constant density flows) equations are decoupled from the velocity field. Moreover, th...
متن کاملTowards Petascale Large Eddy Simulation of Reacting Flow
A novel computational methodology, termed “Irregularly Portioned Lagrangian Monte Carlo-Finite Difference” (IPLMCFD) is developed for large eddy simulation (LES) of turbulent flows. This methodology is intended for use in the filtered density function (FDF) formulation and is particularly suitable for simulation of chemically reacting flows on massively parallel platforms. The IPLMCFD facilitat...
متن کاملLarge-Eddy Simulation of Turbulent Reacting Flows
Numerical simulations of combustion in aircraft engines is quite complex, as it requires an adequate description of liquid fuel injection, liquid fuel atomization, drop breakup, drop dynamics, and evaporation, large-scale turbulent fuel air mixing, small scale molecular fuel air mixing, chemical reactions, and turbulence/chemistry interactions. In the present paper, we have identified three of ...
