The experimental data presented in Part I were analyzed concerning the heat pipe performance characteristics and design. Post-experiment examination of the loosely - wrapped screen wick revealed annular gaps both between the wick and the heat pipe wall and between adjacent screen layers which greatly enhanced the maximum heat capacity of the heat pipe compared to the analytical capillary limit for a tightly - wrapped screen wick. A numerical simulation for the transient heat pipe performances including the vapor region, wick structure and the heat pipe wall is given. Numerical results for continuum transient and steady state operation with multiple heat sources were compared with experimental results and found to be in good agreement.
