Query: Effect of an External Electric Field on the Propagation Velocity of
  Premixed Flames   There have been many experimental investigations into the ability of electric
fields to enhance combustion by acting upon ion species present in flames [1].
In this work, we examine this phenomenon using a one-dimensional model of a
lean premixed flame under the influence of a longitudinal electric field. We
expand upon prior two-step chain-branching reaction laminar models with
reactions to model the creation and consumption of both a positively-charged
radical species and free electrons. Also included are the electromotive force
in the conservation equation for ion species and the electrostatic form of the
Maxwell equations in order to resolve ion transport by externally applied and
internally induced electric fields. The numerical solution of these equations
allows us to compute changes in flame speed due to electric fields. Further,
the variation of key kinetic and transport parameters modifies the electrical
sensitivity of the flame. From changes in flame speed and reactant profiles we
are able to gain novel, valuable insight into how and why combustion can be
controlled by electric fields.
