Internal flow patterns of an inclined closed two-phase thermosyphon at critical state: case study II, effect of bond number

摘要

The effects of Bond number (Bo) on internal flow patterns of an inclined, closed, two-phase thermosyphon at critical state are considered in this article. The thermosyphons used employed a glass tube for the evaporator and the adiabatic section, and a copper tube for the condenser section. The internal diameters of the thermosyphon were 10, 12, and 28.5 mm. The aspect ratios were 5 and 30, with inclination angles of 90°, 60°, and 5°(against the Horizontal axis). R123 was used as working fluid, with a filling ratio of 80/100 and 150/100 of The evaporator section.
