A study has been conducted about an effect of a heat transfer enhancement in a downstream region of the backward-facing step using a small amount of mist whose size is a very small. Additionally, we focused a method in which a rod was inserted near the top end of the step in the channel. As the first in this paper, the effect of the mist on the thermal field of the heating surface and the flow field in the channel are studied experimentally. As the second, this paper shows the experimental results of the effect of the inserted rod on the thermal field of the heating surface and the flow field in the channel. In the position of the rod, x-axis was fixed and y-axis was adopted at three points. The greatest the enhancement of the heat transfer was obtained in the case with the mist and the rod position of Y/H=0.6.
