Abstract
In this study, the result of correlative relation between the heat transfer and flow behaviours near wall region downstream of a backward facing step is presented. The instantaneous flow and temperature distributions are measured by using stereo PIV system (2D-3C) and the high-speed infrared thermography at the same time. Using this system, the unsteady flow behaviour in the xy cross section and heat transfer on the heated wall are investigated at Reynolds number of 3,670. In order to discuss the correspondence of the near wall flow and the heat transfer, cross correlation coefficient of instantaneous these distributions is calculated, and it seems that the forward and downwash flows enhances the heat transfer near wall region.
