RESUMO

The present study primarily aims to investigate the heat transfer characteristics of a loop heat pipe/thermosiphon designed for an industrial scale heat recovery application. For this purpose, an experimental setup has been designed and instrumented so that the heat source medium and its operating temperature variations can be simulated experimentally in the laboratory. In addition, a mathematical simulation tool has been developed to support theoretically the physics behind the thermosiphon experimental observations. The thermosiphon model is proposed to be used as a part of a whole heat recovery system model along with the other elements which will simulate the energy system behavior. The credibility and reliability of the model is evaluated using the experimental data and some immeasurable parameters are calibrated accordingly in the model. Using the developed model, the whole range of operation of the thermosiphon is characterized for the relevant application focusing on the more sensitive and effective parameters which are influencing the thermosiphon performance.
