Non-Premixed Filtered Tabulated Chemistry: Filtered Flame Modeling of Diffusion Flames

Fuels, 2021
The flame front filtering is a well-known strategy in turbulent premixed combustion. An extension of this approach for the non-premixed combustion context has been proposed by means of directly filtering counterflow diffusion flamelets. Promising results

A model for premixed combustion oscillations [PDF]

, 1996
Combustion oscillations are receiving renewed research interest due to increasing application of lean premix (LPM) combustion to gas turbines. A simple, nonlinear model for premixed combustion is described; it was developed to explain experimental results and to provide guidance for developing active control schemes based on nonlinear concepts.

Commercial Naphtha Blends for Partially Premixed Combustion [PDF]

SAE International Journal of Fuels and Lubricants, 2013
<div class="section abstract"><div class="htmlview paragraph">Partially Premixed Combustion has shown the potential of low emissions of nitrogen oxides (NOx) and soot with a simultaneous improvement in fuel efficiency. Several research groups have shown that a load range from idle to full load is possible, when using low-octane-number ...
