This paper describes the methods used to obtain the thermal evolution and radiative output during solar flares as observed by the Extreme ultraviolet Variability Experiment (EVE) onboard the Solar Dynamics Observatory (SDO). Presented and discussed in detail are how EVE measurements, due to its temporal cadence, spectral resolution and spectral range, can be used to determine how the thermal pl...

By means of fluctuational electrodynamics, we calculate radiative heat flux between two planar materials respectively made of SiC and SiO2. More specifically, we focus on a first (direct) situation where one of the two materials (for example SiC) is at ambient temperature whereas the second material is at a higher one, then we study a second (reverse) situation where the material temperatures a...

Emissivity is a critical parameter in the rapid thermal processing ~RTP! of semiconductors for temperature control and thermal modeling. It is often considered as a material property that depends on the sample temperature and surface finishing. For a silicon wafer placed in a radiation environment such as a RTP chamber, however, the ambient photons emitted from lamps create electron-hole pairs ...

The subject deals with a reduced model of the conductiveradiative transient transfer in a participating medium. The accuracy of the analytical solution based on the well-known two-flux approximation and expressed with global radiative coefficients is tested in the case of sharp thermal excitation by a heat pulse on the front face of anisotropically scattering media. A very good agreement is ach...

Emperor penguins Aptenodytes forsteri are able to survive the harsh Antarctic climate because of specialized anatomical, physiological and behavioural adaptations for minimizing heat loss. Heat transfer theory predicts that metabolic heat loss in this species will mostly depend on radiative and convective cooling. To examine this, thermal imaging of emperor penguins was undertaken at the breedi...

Radiative cooling, a unique and uncommon passive cooling method for devices operating outdoors, has recently been demonstrated to be effective for photovoltaic thermal management. In this work, we investigate the effect of radiative cooling as a complement to existing passive cooling methods like convective cooling in a related system with much higher heat loads: a high-concentration photovolta...

This work examines the volumetric effect of convection within a packed bed in the presence of collimated irradiation. Using a modified P-1 approximation incorporating a local thermal nonequilibrium (LTNE) model, the energy transportation through convection and thermal conduction, and collimated and diffuse radiative transfer are investigated. The impact of pertinent parameters such as porosity ...

When the technique of invasive microwave hyperthermia is applied to cancer treating, the distribution of microwave thermal field and the effect of the therapy are determined by the type of microwave radiative antenna. The thermal field of biological tissue produced by microwave radiative antenna is investigated in this paper. The distribution of thermal field and specific absorption rate (SAR) ...
