  • Atomic Physics
DEF

The local heat flux density at which fuel burnout takes place.

OBS

burnout heat flux: term and definition standardized by ISO.

Key term(s)
  • burn-out heat flux

Record 3 2005-03-24

English

Subject field(s)
  • Space Physics
  • Remote Sensing
DEF

The taking up of energy from radiation by the medium through which the radiation is passing.

CONT

Interactions between sea-ice, ocean and atmosphere at high latitudes strongly affect the Earth's climate system. These effects include absorption and emission of radiant energy, poleward flux of heat, and modification of ocean density structure that modulates thermohaline circulation.

OBS

absorption: term officially approved by the RADARSAT-2 Terminology Approval Group (RTAG).

French

Domaine(s)
  • Physique spatiale
  • Télédétection
DEF

Phénomène par lequel un corps solide, liquide ou gazeux, retient la totalité ou une fraction seulement d'un flux d'énergie ou de particules.

CONT

Bien que la télédétection passe par les fenêtres atmosphériques, elle est néanmoins quelque peu perturbée par la diffusion et l'absorption dans l'atmosphère.

OBS

absorption : terme uniformisé par le Groupe de travail de la terminologie de RADARSAT-2 (GTTR).

Spanish

Campo(s) temático(s)
  • Física espacial
  • Teledetección
Save record 3

Record 4 2003-03-20

English

Subject field(s)
  • Thermonuclear fusion
  • Atomic Physics
DEF

The change from nucleate to film boiling.

OBS

The vapor film formed between the heated surface and the cooling liquid decreases the heat transfer from surface to liquid so that a maximum occurs in the curve of heat flux density versus temperature difference.

OBS

departure from nucleate boiling: term standardized by ISO.

French

Domaine(s)
  • Fusion thermonucléaire
  • Physique atomique
DEF

Dans le transfert de chaleur entre une paroi chauffante et un fluide, modification du régime de vaporisation entraînant une réduction rapide et importante de l'échange thermique à la paroi par le passage de l'ébullition nucléée à la caléfaction.

OBS

échauffement critique : Terme normalisé par l'ISO.

Spanish
