Explosions in anaesthesia

Leidenfrost explosions

We present a fluid dynamics video showing the behavior of Leidenfrost droplets composed by a mixture of water and surfactant (SDS, Sodium Dodecyl sulfate). When a droplet is released on a plate heated above a given temperature a thin layer of vapor isolates the droplet from the plate. The droplet levitates over the plate. This is called the Leidenfrost effect. In this work we study the influenc...

Combustion Effects in Confined Explosions

Explosions in the operating theatre.

Explosions in operating theatres do not occur frequently, but unless there is constant care and watchfulness, such catastrophies can descend with tragic suddenness, and may result in loss of life or limb. Those who work in operating theatres tend to forget the dangers lurking round the corner. The writer's purpose is to bring these hazards once again to their notice, and to point out afresh som...

Cosmic Explosions (Optical)

One of the principal motivations of wide-field and synoptic surveys is the search for, and study of, transients. By transients I mean those sources that arise from the background, are detectable for some time, and then fade away to oblivion. Transients in distant galaxies need to be sufficiently bright as to be detectable, and in almost all cases those transients are catastrophic events, markin...

Explosions Modeling – A Tutorial

New challenges and problems emerge everyday with the current wave of terrorism. Suicide bombing, and explosions – a phenomenon only believed to be exist in the battlefields – witnessed and experienced by thousands in civil settings. Traditional approaches and conventional solutions often fail to understand the emerging problems, and help us mitigate the effects. When modeling explosions for inv...
