Heat transfer in a centrifugal heat pipe
Abstract
The effect of thermal flux density and vapor pressure on heat transfer in a cylindrical centrifugal heat pipe was studied on a calorimetric test setup with convective heat feeding and removal. A copper heat pipe of 2.8cm inner diameter was tested at a rotation frequency of 96 rev/sec, a mean condensate layer thickness of 0.3 mm, and thermal flux density in the heat transfer sections of 2080 kW/sq m. It was found that as the thermal flux density and pressure increased, the rate of heat transfer increased. An empirical formula was obtained for the heat transfer coefficient in the heat transfer zone as a function of the parameters studied.
