Combustion Instability of a Multi-injector Rocket Engine Using the Flamelet Progress Variable Model
Lei Zhan, Tuan M. Nguyen, Juntao Xiong +2
The combustion instability is investigated computationally for a multi-injector rocket engine using the flamelet progress variable (FPV) model. A C++ code is developed based on Ope…
Mixing and Combustion in a Laminar Shear Layer with Imposed Counterflow
William A. Sirignano
Three-dimensional laminar flow structures with mixing, chemical reaction, normal strain, and shear strain qualitatively representative of turbulent combustion at the small scales a…
Strain Rate and Pressure Effects on Multi-branched Counterflow Flames
Claudia-F. López-Cámara, Albert Jordà Juanós, William A. Sirignano
This study presents methane-air counterflow simulations, in computationally efficient similar form, allowing combustible mixtures to flow from one or both directions in order to le…
Neural Network Flame Closure for a Turbulent Combustor with Unsteady Pressure
Zeinab Shadram, Tuan M. Nguyen, Athanasios Sideris +1
In this paper, neural network (NN)-based models are generated to replace flamelet tables for sub-grid modeling in large-eddy simulations of a single-injector liquid-propellant rock…
Two-phase developing laminar mixing layer at supercritical pressures
Branson Davis, Jordi Poblador-Ibanez, William A. Sirignano
Numerical analysis of a shear layer between a cool liquid n-decane hydrocarbon and a hot oxygen gas at supercritical pressures shows that a well-defined phase equilibrium can be es…
Dynamics of a spatially developing liquid jet with slower coaxial gas flow
Arash Zandian, William A. Sirignano, Fazle Hussain
A three-dimensional round liquid jet within a low-speed coaxial gas flow is numerically simulated and explained via vortex dynamics ( method). The instabilities on the liquid-…
