Although conventional characterizations of heat transfer in turbulent boundary layers may seem to be appropriate starting points for the treatment of heat transfer in more complex turbulent flows, data from existing experimental studies in boundary layer heat transfer in the presence of high free-stream turbulence suggest otherwise. Neither the conventional boundary layer non-dimensional variables St and Re, nor the conventional analogy between momentum transport and heat transfer for turbulent boundary layers in air are adequate for either correlating or modeling heat transfer in these more complex turbulent flows.
