Abstract

At low pressures small temperature and pressure fluctuations in gas controlled heat pipes are related to movement of the vapour - gas interface. Heat loss from this interface to the condenser causes the formation of mist, which must be supported by axial momentum from the vapour beneath it. Vapour and mist, transported by convecting gas to the cold parts of the condenser, can solidify and in some circumstances can isolate the heat pipe from the pressure control system. Cesium's low latent heat of vaporisation makes it less stable than sodium. Caesium displays complex pulsations in the condenser but for sodium this behaviour only occurs with large vapour flows.
