To investigate the heat transfer augmentation mechanisms by the turbulence promotor, some experimental studies on the heat transfer were made concerning with the separated and reattached flow regions associated with a backward facing step. As the results, heat transfer characteristics of the recirculation, reattached and new boundary layer formation region were obtained. Especially in the reattached region, the dependency of heat transfer coefficients on Reynolds number changes when Reynolds number exceed 1.5〜2 x10^4, in consequence of a transition of separation shear layer. But in the recirculation region, heat transfer characteristics have little concern with the transition.
