Unpolished stainless steel emissivity

WebEmissivity is a measure of how efficiently an object radiates heat, i.e. how well the surface of an object “tells the truth” about its temperature. Emissivity values range from 0 (a theoretically perfect mirror that reflects all energy) to 1 (a theoretical object called a blackbody that perfectly absorbs and radiates all energy). Notice that the emissivity … WebJul 10, 2014 · The normal spectral emissivity of materials is of considerable interest for both practical and scientific reasons. The measurement methods for spectral emissivity are mainly categorized into two groups: (a) comparison between spectral radiation intensities measured from the sample and a blackbody and (b) spectral reflectance measurements ...
