摘要: Employing a novel microwave plasma-assisted combustion (PAC) facility, we conducted comparative study on PAC of premixed and nonpremixed methane/air mixtures. Results showed that three different reaction zones (plasma zone, hybrid plasma-flame flame zone) exist, regardless the fuel injection patterns or nonpremixed. Different had optical emission spectra for zones, with major difference being presence absence emissions from CH C2. A U-shaped ignition curve plasma power versus equivalence ratio was observed in PAC, whereas an approximately linear increasing line PAC. Pulsed cavity ringdown spectroscopy also utilized to measure absolute number densities ground state OH(X) radicals both patterns. density profiles along propagation direction between
