Heat transfer and flow in high-temperature alkali-metal heat pipes
Abstract
An experimental study of the dynamics of heat pipes with steel wool and metal fiber wicks, in particular of startup and transition from one operating mode to another, is presented. The dynamics effect of the initial heat flux in the evaporator when NaK is the working fluid is determined. The effect of interaction between the liquid and vapor phases on the heat and mass transfer from the vapor condensing on the pipe wall is analyzed.
