Alphabetical list of terms

Record 1 2011-03-03

English

Subject field(s)
  • Freezing and Refrigerating
  • Cooling and Ventilating Systems
DEF

Cooling a space [object or substance] air cooled by natural convection.

OBS

Cooling system... In some cases direct contact with ambient air(free convection) may be sufficient; in other cases it may be necessary to employ forced convection...

French

Domaine(s)
  • Congélation, surgélation et réfrigération
  • Systèmes de refroidissement et de ventilation
DEF

Refroidissement par de l'air ou un gaz circulant par convection naturelle sur une surface froide.

CONT

Refroidissement par l'air ambiant. Il est souvent suffisant pour les moteurs de petite puissance : la transmission de chaleur est en général favorisée par la présence d'ailettes qui augmentent considérablement la surface d'échange entre organes et air.

Record 2 2010-04-27

English

Subject field(s)
  • Weather Stations and Meteorological Instruments and Equipment
  • Scientific Instruments
DEF

A psychrometer in which the ventilation required for rapid evaporation from the wick, and concomitant cooling of the wet bulb, is provided by the natural convective motions of the air surrounding the bulb.

CONT

Psychrometer: An instrument designed for determining the relative humidity. ... A non-ventilated psychrometer relies on the natural movement of air for ventilation, whereas a ventilated psychrometer relies on artificially circulated air (eg sling psychrometer).

OBS

The dry and wet bulb temperatures are measured using psychrometers. Most common are those using two mercury thermometers, one of them having the bulb covered with a wick saturated with distilled water, and which measures a temperature lowered due to the evaporative cooling. When they are naturally ventilated inside a shelter, problems can arise if air flow is not sufficient to maintain an appropriate evaporation rate and associated cooling. The Assmann psychrometer has a forced ventilation of the wet bulb and dry bulb thermometers.

OBS

The term "natural circulation psychrometer" is to be contrasted with "forced circulation psychrometer".

Key term(s)
  • simple psychrometer
  • non ventilated psychrometer
  • natural ventilated psychrometer

French

Domaine(s)
  • Stations, instruments et équipements météorologiques
  • Instruments scientifiques
DEF

Psychromètre dont la ventilation du bulbe est assurée par les mouvements convectifs de l'air à l'intérieur de l'abri météorologique.

CONT

Il existe trois grands types de psychromètres : tous sont gradués et l'information est obtenue par lecture directe. - à ventilation naturelle (sous abri) : La vitesse de ventilation n'est pas contrôlée. Ce sont les moins précis et les tables psychrométriques établies pour ce type d'appareils se basent le plus souvent sur une vitesse du vent de 1,5 m/s. - psychromètres frondes [...]; - psychromètres à aspiration [...]

OBS

Il existe deux types principaux de psychromètres : les uns sans ventilation forcée sont utilisés dans l'abri météorologique [...]; les autres, munis d'une ventilation forcée [...]

OBS

S'emploie par opposition au «psychromètre à circulation forcée».

Record 3 2003-06-17

English

Subject field(s)
  • Orbital Stations
CONT

Cooling is provided via passive radiation and heat exchange to the cabin environment, forced avionics air cooling via rear interfaces with the Rack avionics air loop, or water cooling. Drawer payloads interface at the rear for power, data, and avionics air.

OBS

drawer payload: term officially approved by the International Space Station official approval Group (ISSOAG).

French

Domaine(s)
  • Stations orbitales
OBS

tiroir de charge utile : terme uniformisé par le Groupe de travail de la terminologie de la Station spatiale internationale (GTTSSI).

Record 4 2001-07-13

English

Subject field(s)
  • Orbital Stations
CONT

The subsystem provides forced air cooling to all facility modules via the related air ducts connected to the AAA [Avionics Air Assembly], with the exception of the EC' s [Experiment Containers], which are cooled via the dedicated Secondary Water Loop Assembly(SWLA).

OBS

forced air cooling : term officially approved by the International Space Station official approval Group(ISSOAG).

PHR

Forced avionics air cooling.

French

Domaine(s)
  • Stations orbitales
OBS

refroidissement à air forcé : terme uniformisé par le Groupe de travail de la terminologie de la Station spatiale internationale (GTTSSI).

Record 5 2000-10-26

English

Subject field(s)
  • Aircraft Propulsion Systems
OBS

... engines of low horsepower can be cooled sufficiently by the passing airstream in flight. The ram effect of the air takes care of cooling the front part of the cylinder, but the rear area suffers from poor cooling since the air is not forced to flow around that surface.

French

Domaine(s)
  • Propulsion des aéronefs

Record 6 2000-06-06

English

Subject field(s)
  • Atmospheric, Climatic and Meteorological Phenomena
DEF

An approximately stationary cloud, or standing cloud, on or hovering above an isolated mountain peak. It is formed by the cooling and condensation of humid air forced up over the peak.

OBS

The term "cap cloud" is also used to refer to "pileus" with a cap-like form; in this second use, "cap cloud" becomes a descriptive expression.

French

Domaine(s)
  • Phénomènes météorologiques, climatiques et atmosphériques
DEF

Nuage stationnaire situé sur une montagne ou au-dessus d'un sommet de montagne isolé; synonyme de pileus.

OBS

Ne pas confondre le «nuage en capuchon» avec les «pileus», nuages accessoires qui ont la forme soit d'un capuchon soit d'un bonnet.

Spanish

Campo(s) temático(s)
  • Fenómenos meteorológicos, climáticos y atmosféricos
DEF

Nube estacionaria situada en, o sobre, un pico montañoso aislado; es un caso particular de pileus.

Record 7 1999-05-02

English

Subject field(s)
  • Meteorology
  • Atmospheric, Climatic and Meteorological Phenomena
CONT

All clouds, from the puffy cumulus to the wispy cirrus, is a portion of air that has condensed into visible moisture. Cooling of such a portion of air to its dew point is by far the main reason for cloud formation. The main cause for the cooling lies in some process which causes air to rise or be forced upward. Large warm air masses may slide up the slope of a colder heavier mass of air. As the warmer air overrides the cooler, the warm air expands and is cooled itself by the expansion of air molecules, thus finally reaching a dew-point temperature resulting in widespread cloudiness. All clouds consist of minute water droplets, ice crystals, or a combination of both.

OBS

The term "cloud formation", in cloud physics, can also mean "a particular arrangement of cloud, a striking development of a cloud".

French

Domaine(s)
  • Météorologie
  • Phénomènes météorologiques, climatiques et atmosphériques
CONT

Notions sur la formation des nuages. S'il est suffisamment refroidi, l'air chargé de vapeur d'eau devient saturé; un refroidissement plus poussé peut en provoquer la condensation sur des corpuscules d'impuretés en suspension dans l'atmosphère (noyaux de condensation), entraînant ainsi la formation des gouttelettes d'eau qui constituent les nuages.

OBS

Ne pas confondre la «formation des nuages» avec la «formation nuageuse», deux notions qui incidemment se rendent par le même terme en anglais «cloud formation».
