Three-dimensional, Rotational Flamelet Closure Model with Two-way Coupling
William A. Sirignano
A new flamelet model is developed for sub-grid modeling and coupled with the resolved flow for turbulent combustion. The model differs from current models in critical ways. (i) Non…
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…
Physics-Aware Neural Network Flame Closure for Combustion Instability Modeling in a Single-Injector Engine
Zeinab Shadram, Tuan M. Nguyen, Athanasios Sideris +1
Neural networks (NN) are implemented as sub-grid flame models in a large-eddy simulation of a single-injector liquid-propellant rocket engine with the aim to replace a look-up tabl…
Liquid-jet instability at high pressures with real-fluid interface thermodynamics
Jordi Poblador-Ibanez, William A. Sirignano
The injection of liquid fuel at supercritical pressures is a relevant topic in combustion, but usually overlooked. In the past, the wrong assumption whereby the liquid experiments…
A Volume-of-Fluid method for variable-density, two-phase flows at supercritical pressure
Jordi Poblador-Ibanez, William A. Sirignano
A two-phase, low-Mach-number flow solver is created and verified for variable-density liquid and gas with phase change. The interface is sharply captured using a split Volume-of-Fl…
