Turbulent shear stress and heat flux were measured using a hot-wire anemometer in the separated, reattached, and redeveloped regions of an axisymmetric incompressible air flow over a longitudinal circular cylinder having a blunt leading edge. The characteristic features of a turbulent heat flux are detected to be quite different from those of a turbulent shear stress, and in the turbulent boundary layer downstream from the reattachment point, the development of the turbulent heat flux is much quicker than that of the turbulent shear stress.
