Jet-Ventilation PDF

You can visit our cookie privacy page for more information. Background A jet or spray fire is a turbulent diffusion flame resulting from the combustion of a fuel continuously released with some significant momentum in a particular direction or jet-Ventilation PDF. Jet fires represent a significant element of the risk associated with major accidents on offshore installations. The rapid development of a jet fire has important consequences for control and isolation strategies.

Das vorliegende Buch stellt erstmals das gesamte Spektrum der normo- und hochfrequenten Jet-Ventilation dar. Nach der Darstellung der experimentellen Grundlagen und Überlegungen zum Wirkungsmechanismus werden die einzelnen Formen der Jet-Ventilation, die Applikationsmöglichkeiten und die gebräuchlichen Jet-Respiratoren im Detail beschrieben. Der zweite Teil des Buches behandelt die klinischen Einsatzmöglichkeiten der Jet-Beatmung, sowohl intraoperativ (mikrolaryngeale- und Thoraxchirurgie, Bronchoskopie und Stentimplantation) als auch in der Intensiv- und Notfallmedizin. Ein eigenes Kapitel ist dem Einsatz in der Pädiatrie gewidmet. Es wird weiters auf das Monitoring eingegangen, hämodynamische Auswirkungen, mögliche Komplikationen und die Grenzen der Jet-Ventilation werden kritisch beleuchtet.

The properties of jet fires depend on the fuel composition, release conditions, release rate, release geometry, direction and ambient wind conditions. Low velocity two-phase releases of condensate material can produce lazy, wind affected buoyant, sooty and highly radiative flames similar to pool fires. Sonic releases of natural gas can produce relatively high velocity fires that are much less buoyant, less sooty and hence less radiative. Promote the use of a consistent methodology for evaluation of jet fire hazards. The main source of detailed information on the characteristics of jet fires covered in the reports on the programme of jet-fire research co-funded by the European Community. JIP on releases of ‚live‘ crude oil containing dissolved gas and water.

The free flame releases, of crude oil only, were not able to sustain a stable flame and one of the mixed fuel releases was also unstable. All the flames were particularly luminous compared with purely gaseous jet flames and generated large quantities of thick black smoke, mainly towards the tail of the flame. 200 kW m-2 to 400 kW m-2. Typical values were in the range 50 kW m-2 to 400 kW m-2. Gosse, 1999 carried out a separate JIP to quantify the hazards posed by realistic releases of ‚live‘ crude oil containing dissolved gas and water.
