This paper shows the effects of the longitudinal vortex which was generated by a triangular plate inserted in a pipe on the heat transfer enhancement. The longitudinal vortex moved spially downstream. The local heat transfer distribution was depended on the longitudinal vortex. We discuss the circumferential variations of the heat transfer enhancement rate for various discrete locations on downstream region in the pipe. Consequently, we obtained the heat transfer enhancement mechanism on various locations.
