Turbulent combustion modelling
Progress in Energy and Combustion Science, 1988Abstract This paper attempts to review and discuss the current status of the art in turbulent combustion modelling. A description of our present physical and experimental knowledge of the structure of turbulent flames is presented first in order to help the further discussions of models on a physical basis.

Progress in Energy and Combustion Science, 2002
Numerical simulation of flames is a growing field bringing important improvements to our understanding of combustion. The main issues and related closures of turbulent combustion modeling are reviewed. Combustion problems involve strong coupling between chemistry, transport and fluid dynamics.

Combustion Modeling in SI Engines with a Peninsula-Fractal Combustion Model
SAE Technical Paper Series, 1996<div class="htmlview paragraph">In premixed turbulent combustion models, two mechanisms have been used to explain the increase in the flame speed due to the turbulence. The newer explanation considers the full range of turbulence scales which wrinkle the flame front so as to increase the flame front area and, thus, the flame propagation speed ...

Counterflow spray combustion modeling
Combustion and Flame, 1989A fuel spray planar counterflow flame has been modeled by means of a low-Mach-number boundary layer approach. The model considers density variations and full coupling between the two phases by means of a hybrid Eulerian-Lagrangian formulation, with droplet drag and vaporization.

LES Modeling of Scramjet Combustion
44th AIAA Aerospace Sciences Meeting and Exhibit, 2006The physics of supersonic combustion is analyzed in order to derive a new subgrid scale model for Large Eddy Simulation. Anisotropy associated to the directional Mach number typical of supersonic flows (i. e., M > 1 in only one direction) is explicitly considered by means of non-dimensionalized Navier-Stokes equations.

Modeling Combustion of Hydrazinium Nitroformate
38th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2002Combustion of hydrazinium nitroformate (HNF), N2H5C(NO2)3, has been modeled and the resultscompared with experimental observations including steady regression rate (pressure, initial temperature, and radiant flux sensitivities), surface temperature, and linear frequency response to radiation.

Supersonic Combustion: Modelling and Simulations
14th AIAA/AHI Space Planes and Hypersonic Systems and Technologies Conference, 2006Mixing and combustion of supersonic reacting flows are currently under investigation for new generation launchers and trans-atmospheric vehicles. Experimental results with hydrogen injected at Mach 2.5 in a Mach 2 airstreams showed combustion taking place just in ∼0.6 m: this indicates that supersonic combustion is very efficient.
