Where innovation starts

/ Department of Mechanical Engineering – Combustion Technology

The potential use of non-equilibrium plasma for ignition and

combustion control has garnered increasing interest due to

the possibility of plasma-assisted approaches for ignition

and flame stabilization. During the past decade, significant

progress has been made toward understanding the

mechanisms of plasma–chemistry interactions, energy

redistribution and the non-equilibrium initiation of

combustion. The main ideas are the possibility to apply

electric fields for stabilization of the flames, reducing soot

formation, increasing flame velocity, extending flammability

limits.

Two burner head designs will be examined to study the

effect of the plasma location on the flame characteristics at

the same operating conditions.

Experimental study

1D flat flame experimental setup is considered in this study

for better understanding of the flame behavior under

plasma condition as well as validation of the plasma/flame

simulation results. The schematic of the experimental

setup is shown in figure (1), consisting of two parts; the

plenum chamber(bottom) and burner head (top). The goal

of this setup is to create a uniform flow toward the burner

head to ensure 1D flat flame configuration.

Numerical study

One dimensional Plasma-flame interaction with reduced

chemistry using COMSOL software for single hole (0.5mm

diameter) to study the effect of the non-equilibrium plasma

on the emission, temperature and flame stabilization.
