Radiative cooling is a natural process to cool down surfaces through the rejection of thermal radiation using outer space as cold sink, taking advantage transparency atmospheric windows (8–14 μm), which partially matches infrared band. With development new materials that have high reflectivity solar radiation, daytime radiative can be achieved. This phenomenon depends on optical properties surf...

Cooled exhaust gas recirculation (EGR) is a very effective method to reduce nitrogen oxide emissions of diesel engines. However, due to particulate matter and other components present in diesel exhaust gas, EGR coolers are highly prone to fouling. As different soot deposition mechanisms are acting inside the coolers, various model cooler experiments were performed to clarify their contribution ...

Monolithically integrated active cooling is an attractive way for thermal management and temperature stabilization of microelectronic and optoelectronic devices. SiGeC can be lattice matched to Si and is a promising material for integrated coolers. SiGeC/Si superlattice structures were grown on Si substrates by molecular beam epitaxy. Thermal conductivity was measured by the 3v method. SiGeC/Si...

Aperiodic photonic crystals can open up novel routes for more efficient photon management due to increased degrees of freedom in their design along with the unique properties brought about by the long-range aperiodic order as compared to their periodic counterparts. In this work we first describe the fundamental notions underlying the idea of thermal emission/absorption control on the basis of ...

Thermal management is a major challenge for new generation turbofan aero-engines. One of the most promising heat exchangers are so-called surface air-cooled oil coolers (SACOCs). In this study, an experimental methodology proposed and implemented in order to characterize SACOCs mounted bypass ducts. Three different SACOC geometries have been characterized under same nominal operating point, whi...
