Advanced Heat Transfer: Radiative Exchange

This lecture covers advanced topics in heat transfer, focusing on radiative exchange phenomena. The instructor discusses incident radiation, spectral transmittance, and assumptions for no scattering. The lecture delves into predictions from electromagnetic wave theory, Fresnel's equations, and directional hemispherical reflectivity. Various scenarios with windows, coatings, and multiple parallel windows are analyzed. The enclosure theory and the behavior of radiosity in different surfaces are explored. The lecture concludes with examples of reflectance, transmittance, and absorptance calculations for single-layer and multiple parallel windows.
