Decaying Process of Wall-Stabilized Air Arc Contaminated with Plastic Vapor

Thermal Plasma Generators with Water Stabilized Arc

Electric arc stabilized by a vortex of liquid, mostly water, is used in a special type of plasma torch for generation of thermal plasma jet with extreme plasma parameters. The paper presents analysis of properties and processes of water stabilized arcs and discusses differences from common gas stabilized arcs. Plasma torch utilizing stabilization of arc column by combination of gas flow and liq...

Exact simulation of Hawkes process with exponentially decaying intensity

We introduce a numerically efficient simulation algorithm for Hawkes process with exponentially decaying intensity, a special case of general Hawkes process that is most widely implemented in practice. This computational method is able to exactly generate the point process and intensity process, by sampling interarrivaltimes directly via the underlying analytic distribution functions without nu...

Runway Extension With a Vegetated mechanically Stabilized Earth Wall (VMSEW)

Biotrickling Filtration of Air Contaminated with 1-Butanol

The removal of high concentrations of 1-butanol in an air stream was evaluated with a biotrickling filter for potential application to an industrial off-gas. Experiments were conducted on a laboratory-scale system, packed with perlite, in a co-current downward mode with constant recycling of water. The performance was monitored for different inlet concentrations and empty bed residence times du...

Arc Cross-section Determination of Convection Stabilized Arcs

Convection stabilized high current arcs are found in extinction chambers of AC and DC circuit breakers. Such arcs have a radially flat temperature profile with a sharp drop towards the surrounding cold gas. This is because a large fraction of the emitted radiation is reabsorbed at the edge of the arc column. Therefore, it is reasonable to characterize an arc of this type by its cross-section A....
