| Popis: | To improve the ignition and combustion performance of aviation kerosene, two-channel gliding arcs plasma was adopted to crack kerosene into active components, such as gaseous light hydrocarbons and H2. The influence of carrier gas flow rate on discharge characteristics and cracking effects were investigated. Experimental results indicate that, compared to single channel discharge, the power of two-channel gliding arcs discharge is greater while the arcs cover twice as much area as that of single channel discharge. The cracking rate of two-channel discharge plasma is greater than that of single channel discharge while it shows an upward trend with greater carrier gas flow rate. Among the main components of cracking gas, the molar percentage of hydrogen is the highest and exceeds 50%. Greater carrier gas flow rate would result in lower molar percentage of hydrogen. Interestingly, the ethyl group prefers to form C2H2 as the carrier gas flow rate increases in the two-channel gliding arcs discharge while the molar percentage of C2H2 and C2H4 changes inconspicuously in the single channel discharge. |
