Abstract
A variable conductance heat pipe with a length to diameter
ratio of 96 to 1 was designed and constructed. The performance
characteristics of both the conventional and gas loaded
variable conductance modes of operation were studied. Particular
emphasis was placed upon investigating the gravitational
effects in the variable conductance mode. Heat inputs were
varied from ten to fifty watts for horizontal and vertical
operating positions. Methanol was used as the working fluid
with either helium or krypton used as the non-condensible gas.
Condenser temperature profiles and liquid crystal pictures,
showing the effects of gravity, are presented for the various
operating modes.
