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.
