Heat transfer performance of an anodized two-phase closed thermosyphon with refrigerant as working fluid

Mathematical Modeling of Thermal Modes of Closed Two-Phase Thermosyphons with Refrigerant R600A

“…It should be noted that eddy currents reduce the efficiency of heat transfer of closed two-phase thermosyphons. The comparison (Fig.3) between numerical results and the experimental [6] confirms the accuracy of the simulations. The results of mathematical modeling are in good agreement with the experimental data.…”

“…Modern studies of heat transfer through a two-phase closed thermosyphon mainly represented by experimental study of heat and mass transfer processes [3][4][5][6], at the same time, the number of works involving mathematical modeling of these processes is insignificant [7,8].…”

“…The purpose of work is mathematical modeling of heat transfer in two-phase thermosyphon rectangular cross-section with the package ANSYS FLUENT [6] and comparison between numerical modeling and experimental data.…”

Characterisation of a grooved heat pipe with an anodised surface

“…The cleaning process involves solid particle removal, chemical cleaning and desmutting. The detailed process of cleaning and anodising is found in the previous study [19,20]. Later, anodisation is performed to coat the inner wall of the grooved surface.…”

Investigation of two-phase thermosyphon performance filled with modern HFC refrigerants

“…Considering the different working principle and flow pattern inside a revolving heat pipe, results of this study cannot be translated directly to TPCTs. Some of the researches deal with natural refrigerants, like Solomon et al [13].They investigated an anodized TPCT filled with a blend of propane (R290) and is obutane (R600a). More recent works are concentrated on using mixtures as TPCT working fluids, like in [14] where blend of fusel oil and deionized water was testedit showed approximately 30% thermal resistance decrease relatively to pure water.…”
