Modeling study of the counterflow argon plasma reactor operated in atmospheric air surroundings

For an argon plasma jet reactor with counterflow argon injection but operated in air surroundings, modeling results show that a great amount of ambient air will be entrained into the plasma reactor. The location and shape of the quench layer with steep temperature gradients, as well as the flow pattern inside the reactor, depend strongly on the momentum flux ratio of the plasma jet to the counterflow-injected cold gas.
