An experimental study was made in order to clarify time-mean and instantaneous heat transfer performances near the separation point upstream of a forward facing step. In the case of the laminar boundary layer, the separation point was found to fluctuate almost in accordance with a normal distribution by small velocity fluctuation in the free stream. The Reynolds analogy law between the local shearing stress and heat flux was also found to be not applicable at the separation point for both laminar and turbulent boundary layers. For turbulent boundary layers, the position of the separation point is found to be very close to the step and its fluctuation region is very wide and has normal distributions.
