Ein Messsystem zur Bestimmung von Partikeltemperaturen in Druckkohlenstaubflammen
… is the two colour pyrometrie. Particles heat radiation is collected with a glass fibre and detected in an optical unit. Data are sampled and processed with a PC. An existing pyrometer has been optimised for the application to pulverised coal combustion and a new software for data …

Demand for Extinguishing Media in Manual Fire Fighting
… a low-pressure and a high-pressure nozzle. The heat stress on the fire fighters was also studied. Apart from water, gaseous extinguishing media were also investigated with regard to the effect of external heat radiation on the required medium concentration.

Heat transfer in silicon - experiments and simulation
The purpose of this thesis is to study the heat transfer in silicon. Silicon is the key semiconductor material, and thermal processing is the traditional method that is used in semiconductor processing. In this research, we can predict the temperature of the silicon wafer during heating. This …

A study of intumescent coatings
… This formulation was subjected to various heat-radiation intensities using an ISO ignitablilty apparatus. The behaviour of the intumescence, process observed was explained by a simple theoretical model. The model of Buckmasterv Anderson and Nachman was used and several new results were …

Non-equilibrium fluctuation induced-phenomena in quantum electrodynamics
… and waves. Specifically, we study radiative heat transfer and Casimir forces by applying the scattering formalism that expresses results solely in terms of the classical scattering matrices of the objects. For example, we obtain exact formulas for the heat radiation emitted by long …

Untersuchung zur Verbesserung des Wärmetransports durch flüssiges Blei im Stabgitter eines Druckwasserreaktors nach einem schweren Kühlmittelverluststörfall
… lead to a core melt down due to missing decay heat removal. If no cooling system can be activated, the residual water inside the reactor vessel will be evaporated soon. The fuel assemblies above the water level will heat up. The heat transport inside the pin bundle without surrounding water is …

Multi-scale thermal remote sensing, machine learning and radiative flux modeling to assess urban overheating
Linnas on palju soojust neelavaid pindu, mis muudavad linna ümbritsevast maapiirkonnast soojemaks. Kuumalaine ajal tõuseb linna õhutemperatuur tasemeni, mis kahjustab inimeste tervist ja heaolu: linn kuumeneb üle. Kliimaprognoosid näitavad, et kuumalained muutuvad sagedasemaks ja intensiivsusemaks. …
