A three-dimensional numerical analysis of natural convection in a toroidal thermosyphon has been performed. The results confirm the experimental observations of three dimensionality, streamwise flow reversal, and secondary motion. The flow reversals reduce the wall friction and buoyancy forces, and consequently have a strong effect on the average axial velocity.
