Record 1 2009-11-09

English

Subject field(s)
  • Modelling (Mathematics)
  • Radiological Physics (Theory and Application)
CONT

Radiative absorption properties of a number of propellants have been determined in the visible and near UV spectral regions. These data are required for evaluating the radiation energy distribution within a bed from a plasma. These data and a radiation propagation code(Monte Carlo, non-sequential ray tracing) will be used to determine the radiative energy distribution within a propellant bed. Heat flux/fluence gages are described that will be used to measure and differentiate between the convective and radiative energy delivered to a propellant bed.

French

Domaine(s)
  • Modélisation (Mathématique)
  • Physique radiologique et applications
CONT

Pour être utilisables dans les codes de propagation des rayonnements, les sections efficaces doivent obligatoirement subir un traitement à la fois physique, numérique et informatique. Celui-ci découle de la nature des informations stockées dans les évaluations, de la nature du problème physique étudié et des méthodes numériques implémentées dans les codes de transport utilisés.

Record 2 2007-09-13

English

Subject field(s)
  • Burners and Steamfitting
DEF

A raw gas burner with a head (or heads) constructed of refractory material.

OBS

The raw gas is ejected from spuds into an opening in the head(s). Combustion heats the head(s) to incandescence, providing a large amount of radiant heat which tends to increase the speed of flame propagation and keep the flame shorter.

Key term(s)
  • radiant head burner

French

Domaine(s)
  • Fumisterie et brûleurs
OBS

Dispositif de chauffage à tube radiant, comprenant une partie brûleur (1) dans laquelle un flux de gaz chaud est généré, et un tube radiant (2) constitué d'un système de tubulure.
