... on the strip width rather than the grating period, which offers a way to design coherent emitters whose emission peaks can be tuned to a specific frequency of interest for particular applications. The high-temperature results suggest that the MP emittance peak changes little at elevated temperatures up to 750...

...Z. M. Zhang; E. T. Enikov; T. Makansi SiGe alloys represent an important type of high-temperature semiconductor material for solid-state energy conversion. In the present study, the near-field radiative heat transfer between heavily doped SiGe plates is investigated. A dielectric function model...

A SiC wafer was used as the reference to test the emittance measurement facility, which includes a heated sample holder, a blackbody source, mirror assembly, a polarizer, and a Fourier-transform infrared spectrometer with different...

...André Felippe Vieira da Cunha; Marcia B. H. Mantelli High temperature thermosyphons are devices designed to operate at temperatures above 400 ° C . They can be applied in many industrial applications, including heat recovery from high temperature air fluxes. After a short literature review, which...

... reflectometer before and after exposure to the high-temperature heat treatment. An interfacial layer ( TaSi x O y ) formed by the diffusion of Si from the substrate into the deposited film was observed using Auger depth profiling, and the effect of this interfacial layer on the reflectance was measured. Using...

... cooling high temperature droplet sprays and atomization Sprays are used to cool hot objects in many industrial processes because of their convenience of use and high heat dissipating ability. For example, one of the major secondary processes carried out in the metallurgical industries...

...Anquan Wang; Michael F. Modest, Fellow ASME The importance of combined Lorentz-Doppler (or Voigt) broadening of spectral lines in high-temperature radiative heat transfer applications is investigated. Employing narrow-band transmissivities as the criterion, the critical total pressure below which...
