A mathematical model of the opposed-jet diffusion flame: Effect of an electric field on concentration and temperature profiles

Validation of a novel numerical model for the electric currents in burner-stabilized methane–air flames

“…Numerical studies on the charged species concentrations have also been conducted, with a special interest in the reaction mechanisms (e.g. [3,16,17]). Prager et al [18] investigated the charged species concentrations of ionized flames to assess the diffusion of the charged species.…”

“…A quasi-neutrality assumption is usually used to compute the concentrations of charged species, to significantly reduce the computational time [4,16]. This assumes the concentration of electrons to balance the charge carried by the ions.…”

Development of a numerical model for the electric current in burner-stabilised methane–air flames

“…These studies have also been replicated numerically, mainly to investigate reaction mechanisms (e.g. [5,18,19]). The numerical research of Prager et al [20] was primarily aimed at studying the charged species concentrations to investigate the diffusion of the charged species.…”

“…Generally, the concentrations of charged species are computed with the use of quasi-neutrality assumption to reduce the computational time [5,18]. This assumption computes the concentration of the electrons by balancing it with the cation concentration to obtain a completely neutral flow.…”

Counter jet stagnation flows

“…Earliest theoretical treatments, e.g. see Spalding (1961), Fendell (1965, Jones et al (1972) and Lifian (1974), were based on assumed flow fields derived from potential theory like the ones derived by Leclerc (1950) or Bird et al (1960). In this way the treatment of fiat diffusion flames can be looked at as being a subject where combustion and flow are treated separately from each other neglecting the diffusion of momentum (viscosity) all together.…”
