A finite element formulation was used to solve the steady-state two-dimensional conduction heat transfer equation in the condenser wall section of an internally finned rotating heat pipe. A FORTRAM program using this method was coupled with the COPES/CONMIN program for sensitivity analysis of design variables and for automated design of the internal heat pipe geometer. With water as the working fluid, numerical results obtained for copper and stainless steel heat pipe condenser sections indicated that for the maximum heat pipe transfer rate, the designer should machine as many fins as the condenser materials and the manufacturing process will allow. A saw tooth profile is preferable to spacing between fins.
