A study has been made of the transient flow and energy transfer in a natural convection loop. In particular, a toroidal thermosyphon has been considered with orientation in a vertical plane that is heated over the lower half and cooled in the upper half. The basic conservation equations have been solved and the velocity and temperature distributions have been obtained which elucidate the phenomena in natural convection loops. The results include stable, as well as unstable configurations.
