According to Harcros, Emisshield Inc's high
emissivity ceramic coating technology has expanded its applications into the petrochemical industry by increasing heat transfer in fired heaters, boilers and incinerators processes.
Referring to (1), M(T) is the thermal
emissivity of the observed object depending on its temperature (W/[m.sup.2]), [sigma] is the Stefan-Boltzmann constant, and T is the temperature of the black body (K), which is equal to the observed temperature.
Emissivity is a material's physical property that defines its ability to release heat through radiation.
For example, the Split Window algorithm and Day/Night algorithm are used for the Moderate Resolution Imaging Spectroradiometer (MODIS), and the Temperature and
Emissivity Separation (TES) algorithm is used for the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) [4-7].
In this review, we discuss the mean free path of the neutrinos and
emissivity of neutrinos from neutron star in Sections 2 and 3, respectively.
[10] and Wu and Yu [11] studied the effects of modified Al on the gloss and IR
emissivity. However, these methods mainly concentrated on the effects of modified filler on LIREC.
(b)
Emissivity spectra of materials present in the synthetic scene.
Each of these models can be classified into direct sky temperature models and atmospheric
emissivity correlations.
Thus, a selective coat is required to have a high absorption ([alpha]) in the solar wavelength range and an accompanying low thermal
emissivity ([epsilon]) in the near infrared (NIR) and far-infrared (FIR) wavelength ranges.
22-23], they are never made from materials whose
emissivity is strongly directional.
The heat sinks seem colder in the images only due to
emissivity, because they have the lowest
emissivity comparing with transformer, inductor or PCB.
The influence of operating temperature,
emissivity of the surface, orientation, and geometries on the total heat loss of the receiver was investigated.
