| Riassunto: | Title screen There was conducted a numerical analysis of heat-transfer in close two-phasethermosyphon of cylindrical form in the condition of admission of warmth on a lowerlid and taking from the high bound of lid. For description of the researched processwas offered the simplified mathematical model, which describes only processes of heatconductivity in system “a corps of thermosyphon – a steam channel – a condensatemembrane”. This formulated task with boundary conditions was decided by the methodof eventual differences using an implicit difference scheme. As a result have got fieldsof temperatures in thermosyphon for typical thermal loads and methods of working. Wasconducted a comparative analysis of fields of temperature in a thermosyphon at differentthermal streams on a lower lid. Was studied an Influence of coefficient of heat emission andbasic geometrical descriptions on forming of the field of temperature in the crossrunner ofthermosyphon. |
