Abstract
In this study, the result of correlative relation between the heat transfer and flow behaviours near wall region in the turbulent boundary layer is presented. The instantaneous flow and temperature distributions are simultaneously measured by using stereo PIV system (velocity distributions of 2 dimensions and 3 components) and the high-speed infrared thermography. Using this system, the unsteady flow behaviours at the xz cross section and heat transfer on the heated wall are investigated in the Reynolds number range from 610 to 2,200. 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 fluctuations of the forward and downwash flows near wall region corresponds to that of the heat transfer enhancement on the heated wall.
