A linear triangular finite element formulation was used to solve the steady state two dimensional conduction heat transfer equation. A FORTRAN IV computer program of the above formulation, employing double precision arithmetic and compact storage techniques, was applied to study heat transfer in an internally finned rotation heat pipe. Results were obtained for water in a copper and stainless steel condenser with varying outside heat transfer coefficient, rotational speed, and fin angle number of fins. Numerical results of the heat transfer rate in the copper condenser were shown to have less than 2 variance to those obtained earlier. A rotating heat pipe designed to operate with a small value of outside heat transfer coefficient experiences no significant increase of the heat transfer rate with an increase in rotational speed, since the value of the outside thermal resistance dominates.
