Zusammenfassung: | Studies of a plasma jet formation and its injection into a propane-air mixture's counterflow have been performed regarding enhancing combustion and ignition by plasma jets. A computational model involves a realistic equation of state, plasma radiation associated with plasma formation inside the plasma generator, and coupling between the internal nozzle and external flow fields. A one-step effective propane-oxygen chemical reaction with energy release was used for modeling of ignition and combustion. Our model uses an Implicit Free-Lagrange method for the computations. The results of computations demonstrate the ignition of propane-air mixtures stimulated by plasma jet generators, each with a power of 15 kW. The incident propane-air stoichiometric mixture temperature is 1000 K. |
