Simulation of active species production in nonequilibrium discharge plasmas

摘要

Production of active species and plasma assisted ignition of hydrocarbons under the action of a high-voltage nanosecond discharge is simulated using new sets of the electron cross-sections for complex hydrocarbons. The applicability of the available chemical kinetic schemes to lower gas temperatures is analysed on the basis of available measurements. The effect of fast gas heating due to generation of active species is discussed for nonequilibrium plasma assisted ignition in the discharges initiated at extremely high electric fields.
