Abstract
Observations were made of the operation of a gas loaded,
variable conductance heat pipe two inches in diameter and sixty
inches long. The heat pipe was operated in the horizontal and
vertical positions while input power was varied from twenty
five to one hundred fifty watts. Liquid crystal thermographic
techniques were used to observe the temperature gradients
existing when non-condensible gases both heavier and lighter
than the working fluid had been introduced. Methanol was used
as the working fluid; krypton and helium were the non-condensible
gases. Isothermal maps, photographs of liquid crystal displays,
and summarized temperature data for the various operating conditions
are presented.
