Some ultra trace gas species present in the upper troposphere and lower stratosphere (UTLS) region at low part-per-billion part-per-trillion mixing ratios are known to have a major effect on atmospheric chemistry climate. Chlorine bromine causing strong ozone depletion sulfur dioxide (SO2) driving aerosol formation processes of high relevance global radiative budget prominent examples. Nitric acid (HNO3) is another species, which is quite important for particle denitrification...
The formation of the cores breaks during wire fast explosion has been studied experimentally. A series shots (wire explosions) was performed with 25-μm and 50-μm diameter copper, nickel, tungsten wires by using current pulse up to 10 kA short-circuit peak about 400 ns rise time. velocity propagation shock wave front expansion core were estimated processing laser shadowgraphs taken at a probe radiation wavelength 532 nm. It shown that appeared sites where initially had defects related...
Summary form only given. The causes of the transverse irregularities (breaks and narrow regions) thermal instabilities in dense cores exploding single wires observed experiment are discussed. A series shots was performed with 25-μπι 50-μπι diameter copper, nickel, tungsten electrically exploded air by using high-power current pulses up to 8 kA short-circuit peak about 400 ns rise time. velocity propagation shock wave front expansion core were estimated processing laser shadowgraphs taken at...
Summary form only given. Distribution of matter in the discharge channel formed upon a nanosecond electrical explosion Al wire vacuum was studied experimentally and theoretically. Simultaneous use optical UV diagnostics numerical results made it possible to distinguish qualitatively different regions channel, such as current-carrying plasma layers region occupied by weakly conducting cold matter. Several series experiments with 25 μm diameter 12 mm long wires were performed; charging voltage...
