In this study, the microstructure and oxidation behaviour of soot from the raw exhaust of a Euro IV test heavy duty (HD) diesel engine is investigated and compared to that of spark discharge soot and hexabenzocoronene (HBC, C42H18). We find a microstructure-controlled reactivity toward oxidation of all three samples in 5% O2 in N2. The spark discharge soot with its fine primary particles and fu...
Ignition of Nanocomposite Thermites by Electric Spark and Shock Wave Report Title Nanocomposite 8Al ·MoO3 thermite particles were prepared using arrested reactive milling and ignited using two experimental techniques. In spark ignition, a monolayer of powder was placed on a conductive substrate and heated in air by a pulsed electrostatic discharge. In shock ignition, an individual particle was ...
A supercritical (SC) nitrogen (N2) switch is designed and tested. The dielectric strength and recovery rate of the SC switch are investigated by experiments. In order to theoretically study the discharge and recovery process of the SC N2 switch under high repetition rate operation, a numerical model is developed. For SC N2 with initial parameters of p = 80.9 bar and T = 300 K, the simulation re...
Using the method of shadow photographing, formation a spark discharge in "tip (cathode)-plane" interval with length 1.5 mm is investigated. Two types shock waves have been registered cylindrical, created when channel expands, and cathode, presumably generated by cathode flares near surface tip electrode. The computational theoretical consideration proposed mechanism carried ou...
