...Nathan B. Crane Pyrometers are commonly used for high temperature measurement, but their accuracy is often limited by uncertainty in the surface emissivity. Radiation heating introduces additional errors due to the extra light reflected off the measured surface. While many types of specialized...

... way for the determination of the true temperature for “in situ” conditions, especially when the optical factors as the emissivity are unknown. It is important to emphasize that besides the true temperature, the pyroreflectometry method provides important parameters in order to characterize...

... as a powder is fed to the reactor. Furthermore, experimental work led to insight on how best to keep the window clean in the course of an experiment. Also, comparisons between output from the numerical model and experimental results show that the solar flux and the ZnO’s thermal conductivity and emissivity...
