Abstract
The present paper puts forward and experimentally tests a hypothesis of correlation between heat transfer and flow characteristics in the near-wall region. Heat transfer in the separation region has been shown to depend linearly on streamwise fluctuations of velocity at the external boundary of the near-wall region (height y/h = 0.12).
