slanted. This is the expected behavior and is in conformance with the hypothesis that ‘strong vapor diffusion activity takes place at the beginning of the startup, and, toward the end, the diffusion weakens leaving the axial conduction in the wall and wick to govern the steady state profile'. Figs 12 and 13 show the transient temperature profiles at a few specified axial locations for QO = 96.6 W and 257.7 W, respectively. The number shown along each of the curves represents the thermocouple location on the heat pipe.
