Startup of a frozen heat pipe in one-g and micro-g environments - A proposed shuttle flight experiment

Peterson, G. P.(Texas A & M University, College Station, United States)
Abstract: An attempt is made to determine how a heat pipe freezes under various low load and/or no load conditions in both one-g and micro-g environments. Also of interest are the mechanisms that can be used to restart the heat pipe after freezing has occurred. Particular attention is given to step function power reductions and the resulting distribution of the working fluid after freezing has occurred and the effect of noncondensible gases on the frozen configuration and the restart characteristics.
