Definition: EMISSIVITY |
EMISSIVITYNoun1. Tendency to emission; comparative facility of emission, or rate at which emission takes place, as of heat from the surface of a heated body. |
"EMISSIVITY" is a common misspelling or typo for: emissive. |
| Domain | Definitions |
Aerospace | A property of a material, measured as the emittance of a specimen of the material that is thick enough to be completely opaque and has an optically smooth surface. (references) |
Electrical Engineering | Ratio of the radiant emittance or radiated flux of a source to the radiant emittance or radiated flux of a black body having the same temperature, it is usually a function of wavelength. Source: European Union. (references) |
| The ratio of the thermal radiant transfer of the radiator to that of a complete radiator at the same temperature ; the ratio of the thermal radiant exitance of the radiator to that of a full radiator at the same temperature. Source: European Union. (references) | |
| The property of emitting heat radiation; possessed by all materials to a varying extent. "Emittance"(cf. No 2407)is the numerical value of this property, expressed as a decimal fractio n, for a particular material. Emittance values range from 0. 05 for brightly polished metals to 0. 96 for flat black paint. Source: European Union. (references) | |
Energy | The ratio of the radiant energy (heat) leaving (being emitted by) a surface to that of a black body at the same temperature and with the same area; expressed as a number between 0 and 1. (references) |
| The property of emitting radiation;possessed by all materials to a varying extent. (references) | |
Mining | The ratio of radiant energy emitted by a body to that emitted by a perfect black body. A perfect black body has an emissivity of 1; a perfectreflector an emissivity of 0. (references) |
Solar | The ratio of the actual amount of electromagnetic radiation emitted by an object to the amount emitted by an ideal blackbody at the same temperature. (references) |
Weather | The ratio of the radiation emitted by a surface to that emitted by a black body at the same temperature. (references) |
