Melting in an external artery heat pipe was observed experimentally in art earth-based system which simulated the micro- or zero-gravity environment in space. The melting process was analyzed with an one-dimensional model. Heat transfer in the heat pipe shell was assumed to be sufficiently greater than in the melting working fluid that temperature variations in the shell could be neglected. Melting of the working fluid was successfully analyzed using the one-dimensional model to track the location of the melting front and to predict the temperature distribution within the fluid. The predictions compared well to both the experimental data and results from a two-dimensional model[1]. The final solid temperature and the melting time are given for various values of the applied heat flux and the radius of the frozen working fluid channel.
