Preliminary experiments with an electro-osmotic heat pipe laboratory model

Preliminary experiments have been performed with a laboratory model of an electro-osmotic heat pipe filled with ethanol. With dismounted electro-osmotic pump, the heat transport through the pipe and the temperature distribution along the pipe wall have been measured. The measurements have been performed as a function of the temperature...

Uniaxial model for a gas loaded variable conductance heat pipe

A new uniaxial model for a gas loaded variable conductance heat pipe (VCHP) is developed. This model takes into account the diffusion at the vapour-gas interface as well as the inertial effects of the moving vapour. Only steady-state conditions are considered. The generally accepted Edwards /Marcus model will be shown to be a first order...

Theory and design of conventional heat pipes for space applications

The scope of this report is: - to give a short description of the possible operation principles and applications of heat pipes - to derive the governing equations for a model of a conventional heat pipe (including the limits to the heat transfer capability) - to describe the theoretical derivation of the formulae for the various thermal...
