In contrast to radiative cooling, the purpose of radiative heating or warming is to block the heat radiation loss from the human body as much as possible. As such, the functional textiles are desired to reflect the IR emitted from the human body on the inner cloth surface as well as reduce...

draw five boundaries about that element, and pixelate them uniformly. Then, project the surrounding faces onto these pixelated boundaries and count the pixels associated with each face to determine how much radiative heating is coming from the surrounding faces, and is irradiating...
(8)–(10) were obtained every 50,000 flowfield solution iterations, and a relaxation factor of 0.3 was applied to the ablation rate. This relaxation factor is required because changing the ablation rate influences the species profiles and temperatures, which impact the radiative heating and Srad ...
Light absorption in conducting materials produces heating of their conduction electrons, followed by relaxation into phonons within picoseconds, and subsequent diffusion into the surrounding media over longer timescales. This conventional picture of optical heating is supplemented by radiative cooling, which ...
In less than 300 s, the glazing panel may change from a heating mode to a cooling one. When a low voltage of ~2.5 V is used to tint the panel, the glazing panel shifts to radiative cooling mode, which reflects 89% of the incoming solar energy (Fig. 10g (middle), "cooling mode")...
55,56). In such rare cases their development may be affected by radiative heating68 enhancing vertical mixing. Regional contrail RF can be close to or above 1 W m−2 (refs. 6,52,69,70,71). Globally averaged, annual mean RF values and uncertainty ranges for persistent contrails ...
Thus, less atmospheric radiative\nheating is estimated near the major source regions (less heating to 0.15\nfrom 0.59Wm2 on a global scale), because of enhanced LW\nwarming at the surface by the synergy of coarser size and aspherical shape....
The pre-factor eSW/eLW is ratio of the wide-band short-wave absorptivity and long-wave absorptivity. Radiative equilibrium follows from combining a steady state condition with the radiative transfer equations. The steady state condition follows by setting the local heating rate to zero. The local ...
As mentioned previously, Si is one of the most thermally conductive semiconductor materials, which is a big advantage for dissipating device joule heating. However, fast thermal roll-over (Fig. 10.4a) is obvious and typical in most demonstrated hybrid devices. The primary cause of serious device...
